Previously, dismissing the ask dialog (via Escape, clicking outside, or
Cancel button) only cleared the UI state without sending an ask_response
to the server. This left the server-side deferred promise unresolved,
causing the agent's askUser() call to hang forever.

Changes:
- PromptModal: prevent click-outside from closing ask modals; Escape and
  Skip button now send "[skipped]" response so the agent unblocks
- App.tsx: Escape key handler sends a response for ask modals instead of
  bare dismissal
- store.actions: answerAsk checks sendThread return value and keeps the
  modal open if the WebSocket send fails
