KRATOS 58e209d021 Sound / completion notifier: terminal bell + OSC-9 on turn completion & awaiting-input (#149) ...

* notify: dep-free terminal bell / OSC-9 completion notifier

* config: notify.mode + notify.focusMode (validated, default off)

* exec: --notify/--no-notify + completion notify on stderr

* tui: focus reporting + completion/awaiting-input notifications

* notify: fire on exec --use-spec completion; headless ignores focus; gate focus-reporting on enabled

* notify: validate --notify value, skip notify on empty ask_user, deterministic resolver tests

Addresses #149 review (CodeRabbit + @Vasanthdev2004):
- parseExecArgs rejects an invalid --notify value (only off/bell/notify/both),
  so a CLI typo errors early instead of silently running with no notification.
- TUI OnAskUser fires AwaitingInput only when len(request.Questions) > 0 — a
  request with no questions auto-resolves without prompting, so the bell/desktop
  notification was a false positive.
- notify resolver tests pass Env: map[string]string{} so Resolve does not fall
  back to os.Getenv (deterministic, not ambient-env dependent).
