**Goal:** Listening UX without real STT.
### Tasks
-- [ ] Implement **global hotkey** manager:
- - [ ] Default **⌘⇧V** (configurable later).
- - [ ] Support **push-to-talk** (start on key down, stop on key up).
- - [ ] Support **toggle** (press to start, press to stop).
-- [ ] Create **HUD** as non-activating centered `NSPanel`:
- - [ ] State **Listening** with **RMS/peak bars** animation (SwiftUI view).
- - [ ] State **Processing** with spinner/label.
- - [ ] Dismiss/cancel with **Esc**.
-- [ ] Implement **AVAudioEngine** capture:
- - [ ] Tap on input bus; compute RMS/peak for visualization.
- - [ ] Resample path ready for 16 kHz mono PCM (no STT yet).
-- [ ] Add dictation **time limit** (default **10 min**, configurable later).
-- [ ] Optional **sounds** for start/stop (toggle in settings later).
-- [ ] Permissions onboarding:
- - [ ] Request **Microphone** permission with Info.plist string.
- - [ ] Show guide for **Accessibility** and **Input Monitoring** (no hard gating yet).

-- [ ] Hotkey works in both modes (push/toggle) across desktop & full-screen apps.
-- [ ] HUD appears centered; **Listening** shows live bars; **Processing** shows spinner.
-- [ ] Cancel (Esc) reliably stops listening and hides HUD.
