[parent] #1339
Problem
ctrl+c swallowed by ask-user/tool-approval overlays; plan-approval overlay has no Esc/deadline (model.go ~2827, plan_approval.go ~26).
Outcome
ctrl+c/Quit falls through overlays; Esc handling + local deadline timer on plan gate.
Acceptance criteria
- Overlay active + ctrl+c quits; expired plan gate dismissible.
Test-first plan
Quit-under-overlay test (expected red).
Impact analysis
TUI overlay state machines only.
