Tests for the epic's new code so the 95% floor holds: ClideSettings.i18n
string/interpolated null-safe + localizedCommandTitle; settings-renderer
localization (section/field/help/select/file, project-scope tag, didUpdateWidget);
extension-activation rollback + settings-contribution unregister; the Dutch
gate check; RootShell applying app.locale on boot; and prompt/conversation
tool-body + file-ref coverage. Also harden the menu toggle re-tap (capture the
button point while stable, then tapAt) so it no longer throws getCenter under
the serial coverage load.

Lay the foundation for the schema-driven settings UI (epic T-444). A new
`settings.open` command (⌘`,`, plus a File-menu and command-palette entry)
opens a centered Settings modal over the dimmed app via the dialog router,
built from the modalSurface* tokens (D-7, no Material). The shell frames the
two regions later tickets fill in — the category rail (T-447) and the
scrolling carded panel (T-448) — and dismisses on ✕, Esc, or barrier tap.
With no category registered yet it shows its empty state, which is the
correct runtime state.
Flesh out the `builtin.settings-ui` stub (was 0.0.0-stub) into a real
extension; ship its en-US i18n catalog. Relabel the theme picker's
`theme.pick` command title from "Settings…" to "Theme…" so the two no
longer collide in the palette (the picker folds into the new panel's
Appearance category in T-452).
Tests: command + ⌘`,` binding registered, shell renders, Esc and close
both dismiss.
