release v2.7.0

Settings panel epic: schema-driven settings engine (modal shell, category
rail, per-field scope tags, cross-category search) with Activity, Keymap,
Appearance, Extensions, and Claude categories; Inter as the default UI font
plus live UI + monospace font pickers (Inter, Fira Mono bundled). Backed by
the ClideSettings facade (D-101) unifying theme, i18n, and fonts behind one
widget-facing read entry, with consumer reads migrated onto it.
