Completes i18n coverage of the conversation surface — the strings the
T-464 migration left as "decorative" English:
- running-indicator verbs (Pondering/Conjuring/… → catalog, Dutch added)
- pane chrome title (primary / secondary N) and banner role
- tool-card titles (Edit → Bewerken) via a tool.name.* key set, with
command/proper-name tools (Bash, Grep, Glob, LS) falling back to the
raw name
- collapser step/edit/agent counters
- the folded-activity ticker (result/error/thinking/image + tool name)
English degrades to the placeholder where a key is absent, so untranslated
or MCP tool names render unchanged. en_us and nl_nl stay at key parity.

A full nl_NL catalog set under assets/i18n/nl_nl/ — all 26 namespaces, key-for-
key parity with en_us. Proper nouns (clide, Claude, Git, font names) and the
Vim mode names stay as-is; everything else is translated. Selectable via
Settings → Appearance → Language. The a11y i18n gate now also asserts the
Dutch pack covers every Tier-0 key, so a locale switch never falls back to
English for a built-in label.

Make the localization usable: an app.locale select (English / Nederlands) in
the Appearance category, applied live by root_shell — it parses app.locale and
calls i18n.setLocale on boot + on settings change (setLocale is a no-op when
unchanged). nl_NL registered in availableLocales. The ui-design skill now
documents the locale-dir config and the rule to design for string-length
variation (translations run ~20% longer; never hard-size to the English label).

Move the catalogs out of lib/kernel/src/i18n/catalog/ into assets/i18n/, and
switch the layout from a `{namespace}_{locale}.json` filename to a per-locale
DIRECTORY: assets/i18n/en_us/{namespace}.json. Adding a language is now just a
new folder (assets/i18n/nl_nl/, nl_be, en_eu, …) of the same namespace files —
no renames — which is cleaner to maintain and mirrors how an external
extension ships its own catalog. AssetCatalogLoader/FileCatalogLoader resolve
`<root>/<locale>/<namespace>.json`; pubspec bundles the locale folder.
