Subject: [PATCH] feat(app): add /thinking command to toggle reasoning in web
 UI

Adds a /thinking slash command to the web session command palette that toggles reasoning summaries (show/hide model reasoning) and shows a toast, mirroring the existing TUI thinking toggle. Adds the new i18n keys to every locale so the i18n parity test passes.
