Implement double-escape session abort matching TUI behavior

- Add double-escape debounce pattern with 1-second timeout
- First escape shows warning, second escape aborts session
- Fix session busy check to handle undefined timeCompleted field
- Add abortSession API call to sessions store
- Show visual feedback in prompt input during debounce
- Remove Escape from filtered keys in prompt-input auto-focus
