feat(client): localize composer hints and rework input command interaction

Unify the /plan claimed hint with the plan placeholder through a locale
namespace, localize slash menu group titles, replace the PermissionSelect
native select with the Menu primitive, add a goal pause verb chain, clamp
anchored popups to the viewport with scroll-into-view and outside-dismiss,
and fix onPasteUpgrade insertedRange to account for the chip trailing gap.
