feat(desktop): broaden hotkey coverage + fold in stray shortcuts

Add rebindable actions for the high-frequency gaps: focus composer, open
model picker, next/prev session, search sessions (⌘⇧F), show files/
terminal tab, and nav→artifacts. Reconcile the duplicate Shift+N new-
session listener into session.new's defaults, and surface the remaining
context-local shortcuts (⌘↵ steer, ⌘L terminal selection, ⌘W close
preview) as read-only rows so the panel is the honest source of truth.
