core: add description to built-in light theme

Theme files saved with /theme save and automatic backups now always
contain every themable option (full snapshot), so a theme file is
self-contained and round-trips exactly regardless of the current
configuration. The diff-only mode and the "-full" argument of
/theme save are removed.

+// TRANSLATION MISSING
+[[themes]]
+=== Themen
+
+A theme is a named bundle of option overrides that can be applied with
+the <<command_weechat_theme,/theme>> command. WeeChat ships a built-in
+`"light"` theme tuned for light-background terminals and supports
+user-defined themes loaded transiently from files.
+
+[[themes_themable_options]]
+==== Themable options
+
+Themes can only set options marked as _themable_. All `*.color.*`
+options are themable by default; a few string options that hold format
+expressions with `+${color:...}+` references (such as
+`+weechat.color.chat_nick_colors+`, `+weechat.look.prefix_error+` or the
+`+buflist.format.*+` formats) are explicitly opted in.
+
+You can list the full themable surface area from the
+<<command_fset_fset,/fset>> buffer with the `+t:themable+` filter.
+
+[[themes_apply]]
+==== Applying a theme
+
+To switch to the built-in light-background theme:
+
+----
+/theme apply light
+----
+
+The current state of every themable option is saved beforehand to a
+backup theme file named like `+backup-YYYYMMDD-HHMMSS-uuuuuu+` in
+directory `+themes+` inside the WeeChat configuration directory, so the
+previous look can be restored at any time with:
+
+----
+/theme apply backup-YYYYMMDD-HHMMSS-uuuuuu
+----
+
+Backup creation can be disabled (not recommended):
+
+----
+/set weechat.look.theme_backup off
+----
+
+If backup is enabled and the backup file cannot be written, the apply
+is aborted before any option is changed.
+
+The name of the last applied theme is stored in
+`+weechat.look.theme+` (informational only; not re-applied at startup).
+
+[[themes_reset]]
+==== Resetting to defaults
+
+To restore the look shipped with WeeChat, reset every themable option
+to its default value:
+
+----
+/theme reset
+----
+
+A backup is written first (same gate as `+/theme apply+`); on backup
+failure the reset is aborted before any option is changed.
+`+weechat.look.theme+` is cleared too.
+
+[[themes_save_delete]]
+==== Saving and deleting user themes
+
+Save the current themable options as a new user theme file:
+
+----
+/theme save mytheme
+----
+
+Every themable option is written, so the file is self-contained and
+applies the exact same look on any WeeChat, regardless of its current
+configuration.
+
+Reserved names (built-in theme names like `+light+` and any name
+starting with `+backup-+`) are refused. Files live at
+`+${weechat_config_dir}/themes/<name>.theme+`.
+
+Rename a user theme (typical use: keep a useful automatic backup
+under a meaningful name):
+
+----
+/theme rename backup-20260525-094210-123456 mybackup
+----
+
+Built-in themes have no file and cannot be renamed; the target name
+cannot match a built-in name or start with `+backup-+`, and the
+target file must not already exist. The `+[info]+` `+name+` field
+inside the file is rewritten so `/theme info` reports the new name
+consistently.
+
+Delete a user theme:
+
+----
+/theme del mytheme
+----
+
+This removes the file on disk; built-in themes cannot be deleted.
+
+[[themes_file_format]]
+==== Theme file format
+
+A theme file is INI-like with two sections:
+
+----
+[info]
+name = "solarized_light"
+description = "Light-background theme inspired by Solarized"
+date = "2026-05-25 09:42:10"
+weechat = "4.10.0-dev"
+
+[options]
+weechat.color.chat = "darkgray"
+weechat.color.separator = "blue"
+irc.color.input_nick = "magenta"
+buflist.format.number = "${color:28}${number}${if:${number_displayed}?.: }"
+----
+
+`+[info]+` is informational metadata shown by `/theme info`. `+[options]+`
+holds the actual overrides; keys are the full option names that would
+appear in `/set`. String values can be enclosed in double or single
+quotes; quotes are stripped at parse time. Non-themable options listed
+in a theme file are refused at apply time and logged to the core
+buffer (so a `.theme` file imported from an untrusted source cannot
+overwrite passwords, autoload lists, or startup commands).
+
+User theme files are never cached: on every `/theme apply <name>` the
+file is parsed, applied, and freed.
+
+[[themes_resolution]]
+==== Resolution order
+
+When `+/theme apply <name>+` is run:
+
+* If `+${weechat_config_dir}/themes/<name>.theme+` exists, the file
+  is parsed and used (it shadows any built-in with the same name).
+* Otherwise the built-in theme registry is consulted; built-ins are
+  registered programmatically by core, plugins and scripts (see the
+  plugin and scripting documentation for `+weechat_theme_register+`).
+
+If neither source provides the name, the apply is refused.

+[[themes]]
+=== Thèmes
+
+Un thème est un ensemble nommé de surcharges d'options qui peut être
+appliqué par la commande <<command_weechat_theme,/theme>>. WeeChat est
+livré avec un thème intégré `"light"` adapté aux terminaux à fond clair
+et permet de charger temporairement des thèmes utilisateur depuis des
+fichiers.
+
+[[themes_themable_options]]
+==== Options modifiables par un thème
+
+Les thèmes ne peuvent modifier que les options marquées comme
+_themable_ (modifiables par un thème). Toutes les options `*.color.*`
+le sont par défaut ; certaines options de type chaîne contenant des
+références `+${color:...}+` (par exemple
+`+weechat.color.chat_nick_colors+`, `+weechat.look.prefix_error+` ou les
+formats `+buflist.format.*+`) sont explicitement déclarées comme
+modifiables.
+
+La liste complète des options modifiables peut être affichée depuis le
+tampon <<command_fset_fset,/fset>> avec le filtre `+t:themable+`.
+
+[[themes_apply]]
+==== Appliquer un thème
+
+Pour basculer vers le thème intégré pour fond clair :
+
+----
+/theme apply light
+----
+
+L'état actuel de toutes les options modifiables est sauvegardé au
+préalable dans un fichier de sauvegarde nommé
+`+backup-AAAAMMJJ-HHMMSS-uuuuuu+` dans le répertoire `+themes+` du
+répertoire de configuration de WeeChat. L'apparence précédente peut
+ainsi être restaurée à tout moment avec :
+
+----
+/theme apply backup-AAAAMMJJ-HHMMSS-uuuuuu
+----
+
+La création de la sauvegarde peut être désactivée (déconseillé) :
+
+----
+/set weechat.look.theme_backup off
+----
+
+Si la sauvegarde est activée et que le fichier ne peut pas être écrit,
+l'application est annulée avant qu'aucune option ne soit modifiée.
+
+Le nom du dernier thème appliqué est conservé dans
+`+weechat.look.theme+` (à titre informatif uniquement ; il n'est pas
+ré-appliqué au démarrage).
+
+[[themes_reset]]
+==== Réinitialiser aux valeurs par défaut
+
+Pour rétablir l'apparence d'origine livrée avec WeeChat, réinitialiser
+toutes les options modifiables à leur valeur par défaut :
+
+----
+/theme reset
+----
+
+Une sauvegarde est écrite au préalable (même garde-fou que
+`+/theme apply+`) ; si la sauvegarde échoue, la réinitialisation est
+annulée avant qu'aucune option ne soit modifiée. L'option
+`+weechat.look.theme+` est également remise à vide.
+
+[[themes_save_delete]]
+==== Sauvegarder et supprimer des thèmes utilisateur
+
+Sauvegarder l'état actuel des options modifiables en tant que nouveau
+thème utilisateur :
+
+----
+/theme save monTheme
+----
+
+Toutes les options modifiables sont écrites, donc le fichier est
+autonome et applique exactement le même aspect sur n'importe quel
+WeeChat, quelle que soit sa configuration actuelle.
+
+Les noms réservés (noms de thèmes intégrés comme `+light+` et tout nom
+commençant par `+backup-+`) sont refusés. Les fichiers sont placés
+dans `+${weechat_config_dir}/themes/<nom>.theme+`.
+
+Renommer un thème utilisateur (usage typique : conserver une
+sauvegarde automatique utile sous un nom plus parlant) :
+
+----
+/theme rename backup-20260525-094210-123456 maSauvegarde
+----
+
+Les thèmes intégrés n'ont pas de fichier et ne peuvent pas être
+renommés ; le nom cible ne peut pas correspondre à un nom intégré ni
+commencer par `+backup-+`, et le fichier cible ne doit pas déjà
+exister. Le champ `+name+` de la section `+[info]+` à l'intérieur du
+fichier est réécrit afin que `/theme info` affiche le nouveau nom de
+manière cohérente.
+
+Supprimer un thème utilisateur :
+
+----
+/theme del monTheme
+----
+
+Cela supprime le fichier sur le disque ; les thèmes intégrés ne
+peuvent pas être supprimés.
+
+[[themes_file_format]]
+==== Format du fichier de thème
+
+Un fichier de thème est de type INI avec deux sections :
+
+----
+[info]
+name = "solarized_light"
+description = "Thème fond clair inspiré de Solarized"
+date = "2026-05-25 09:42:10"
+weechat = "4.10.0-dev"
+
+[options]
+weechat.color.chat = "darkgray"
+weechat.color.separator = "blue"
+irc.color.input_nick = "magenta"
+buflist.format.number = "${color:28}${number}${if:${number_displayed}?.: }"
+----
+
+`+[info]+` est une section de métadonnées informatives affichées par
+`/theme info`. `+[options]+` contient les surcharges réelles ; les clés
+sont les noms complets d'options tels qu'affichés par `/set`. Les
+valeurs de type chaîne peuvent être encadrées par des guillemets
+simples ou doubles ; les guillemets sont retirés à l'analyse. Les
+options non modifiables par un thème listées dans un fichier sont
+refusées au moment de l'application et signalées sur le tampon _core_
+(ainsi, un fichier `.theme` importé depuis une source non fiable ne
+peut pas écraser des mots de passe, des listes d'auto-chargement ou
+des commandes de démarrage).
+
+Les fichiers de thème utilisateur ne sont jamais mis en cache : à
+chaque `/theme apply <nom>`, le fichier est analysé, appliqué, puis
+libéré.
+
+[[themes_resolution]]
+==== Ordre de résolution
+
+Lors de l'exécution de `+/theme apply <nom>+` :
+
+* Si `+${weechat_config_dir}/themes/<nom>.theme+` existe, le fichier
+  est analysé et utilisé (il masque tout thème intégré du même nom).
+* Sinon, le registre des thèmes intégrés est consulté ; les thèmes
+  intégrés sont enregistrés par programmation par le cœur, les
+  extensions et les scripts (voir la documentation des extensions et
+  des scripts pour `+weechat_theme_register+`).
+
+Si aucune des deux sources ne fournit le nom, l'application est
+refusée.

+=== Themes
+
+A theme is a named bundle of option overrides that can be applied with
+the <<command_weechat_theme,/theme>> command. WeeChat ships a built-in
+`"light"` theme tuned for light-background terminals and supports
+user-defined themes loaded transiently from files.
+
+[[themes_themable_options]]
+==== Themable options
+
+Themes can only set options marked as _themable_. All `*.color.*`
+options are themable by default; a few string options that hold format
+expressions with `+${color:...}+` references (such as
+`+weechat.color.chat_nick_colors+`, `+weechat.look.prefix_error+` or the
+`+buflist.format.*+` formats) are explicitly opted in.
+
+You can list the full themable surface area from the
+<<command_fset_fset,/fset>> buffer with the `+t:themable+` filter.
+
+[[themes_apply]]
+==== Applying a theme
+
+To switch to the built-in light-background theme:
+
+----
+/theme apply light
+----
+
+The current state of every themable option is saved beforehand to a
+backup theme file named like `+backup-YYYYMMDD-HHMMSS-uuuuuu+` in
+directory `+themes+` inside the WeeChat configuration directory, so the
+previous look can be restored at any time with:
+
+----
+/theme apply backup-YYYYMMDD-HHMMSS-uuuuuu
+----
+
+Backup creation can be disabled (not recommended):
+
+----
+/set weechat.look.theme_backup off
+----
+
+If backup is enabled and the backup file cannot be written, the apply
+is aborted before any option is changed.
+
+The name of the last applied theme is stored in
+`+weechat.look.theme+` (informational only; not re-applied at startup).
+
+[[themes_reset]]
+==== Resetting to defaults
+
+To restore the look shipped with WeeChat, reset every themable option
+to its default value:
+
+----
+/theme reset
+----
+
+A backup is written first (same gate as `+/theme apply+`); on backup
+failure the reset is aborted before any option is changed.
+`+weechat.look.theme+` is cleared too.
+
+[[themes_save_delete]]
+==== Saving and deleting user themes
+
+Save the current themable options as a new user theme file:
+
+----
+/theme save mytheme
+----
+
+Every themable option is written, so the file is self-contained and
+applies the exact same look on any WeeChat, regardless of its current
+configuration.
+
+Reserved names (built-in theme names like `+light+` and any name
+starting with `+backup-+`) are refused. Files live at
+`+${weechat_config_dir}/themes/<name>.theme+`.
+
+Rename a user theme (typical use: keep a useful automatic backup
+under a meaningful name):
+
+----
+/theme rename backup-20260525-094210-123456 mybackup
+----
+
+Built-in themes have no file and cannot be renamed; the target name
+cannot match a built-in name or start with `+backup-+`, and the
+target file must not already exist. The `+[info]+` `+name+` field
+inside the file is rewritten so `/theme info` reports the new name
+consistently.
+
+Delete a user theme:
+
+----
+/theme del mytheme
+----
+
+This removes the file on disk; built-in themes cannot be deleted.
+
+[[themes_file_format]]
+==== Theme file format
+
+A theme file is INI-like with two sections:
+
+----
+[info]
+name = "solarized_light"
+description = "Light-background theme inspired by Solarized"
+date = "2026-05-25 09:42:10"
+weechat = "4.10.0-dev"
+
+[options]
+weechat.color.chat = "darkgray"
+weechat.color.separator = "blue"
+irc.color.input_nick = "magenta"
+buflist.format.number = "${color:28}${number}${if:${number_displayed}?.: }"
+----
+
+`+[info]+` is informational metadata shown by `/theme info`. `+[options]+`
+holds the actual overrides; keys are the full option names that would
+appear in `/set`. String values can be enclosed in double or single
+quotes; quotes are stripped at parse time. Non-themable options listed
+in a theme file are refused at apply time and logged to the core
+buffer (so a `.theme` file imported from an untrusted source cannot
+overwrite passwords, autoload lists, or startup commands).
+
+User theme files are never cached: on every `/theme apply <name>` the
+file is parsed, applied, and freed.
+
+[[themes_resolution]]
+==== Resolution order
+
+When `+/theme apply <name>+` is run:
+
+* If `+${weechat_config_dir}/themes/<name>.theme+` exists, the file
+  is parsed and used (it shadows any built-in with the same name).
+* Otherwise the built-in theme registry is consulted; built-ins are
+  registered programmatically by core, plugins and scripts (see the
+  plugin and scripting documentation for `+weechat_theme_register+`).
+
+If neither source provides the name, the apply is refused.
