feat(recording): add zoom marker shortcut while recording

[muhammad-a-dev]

Summary

Adds a recording-time zoom marker shortcut so authors can mark zoom points while recording.

• While recording is active, registers global shortcut CommandOrControl+Alt+Z (500ms throttle).
• On press, records a cursor telemetry sample with interaction type manual-zoom at the current cursor position and capture time (only when cursor capture is active).
• Unregisters the shortcut when recording stops and on app before-quit.
• On fresh recording open, converts manual-zoom markers into manual zoom regions and skips auto-suggest when manuals were applied.

Fixes #352

Notes vs closed draft #353

This revives the approach from closed draft PR #353, adapted to current main:

• Shortcut registration lives in electron/recordingZoomShortcut.ts and is wired from electron/ipc/handlers.ts on recording state changes (avoids a large electron/main.ts edit).
• Editor wiring uses the current hooks/project modules (useFreshRecordingManualZoom, timeline/project controllers, UI refs) rather than the older monolithic VideoEditor path.
• manual-zoom is allowlisted in normalizeCursorTelemetrySamples so markers are not stripped.
• Click-effect paths on current main already use interaction allowlists, so manual-zoom is naturally excluded without extra !== "manual-zoom" patches.
• electron/electron-env.d.ts still needs | "manual-zoom" added to the global CursorTelemetryPoint union (ipc and video-editor type unions are updated). Runtime and feature typing use electron/ipc/types.ts and src/components/video-editor/types.ts.

Testing

• npx vitest run src/components/video-editor/timeline/recordingZoomMarkers.test.ts (3 tests passed locally after npm install --ignore-scripts).
• Manual recording shortcut / end-to-end zoom region application not exercised in this environment.

Summary by CodeRabbit

• New Features
  • Added a keyboard shortcut (Command/Ctrl+Alt+Z) during recording to mark moments for zooming.
  • Fresh recordings now receive manual zoom regions at marked moments, centered on the cursor and arranged to avoid overlaps with existing zoom regions.

📝 Walkthrough

Walkthrough

The recording shortcut captures manual zoom markers in cursor telemetry. The editor tracks eligible fresh recordings, converts their markers into zoom regions, and adds those regions to the timeline.

Changes

Manual recording zoom

Layer / File(s)	Summary
Capture markers from the recording shortcut electron/ipc/types.ts, electron/ipc/cursor/telemetry.ts, electron/recordingZoomShortcut.ts, electron/ipc/handlers.ts	The cursor interaction type accepts manual-zoom, and the capture function records a marker when cursor capture is active. Recording-state changes register or unregister a throttled global shortcut.
Track eligible recording paths src/components/video-editor/state/useEditorUiState.ts, src/components/video-editor/VideoEditor.tsx, src/components/video-editor/project/*	Editor state tracks pending and processed manual-zoom paths. Source loading and media import set the pending path; project lifecycle operations reset the tracking refs.
Build and apply manual zoom regions src/components/video-editor/types.ts, src/components/video-editor/timeline/recordingZoomMarkers*, src/components/video-editor/hooks/useFreshRecordingManualZoom.ts, src/components/video-editor/hooks/useTimelineEditingController.ts	The timeline converts manual marker samples into bounded, non-overlapping regions. The hook applies regions for eligible recordings, and tests cover marker placement, reserved spans, adjacent markers, and focus clamping.

In `@electron/ipc/cursor/telemetry.ts`:
- Around line 271-277: Update pushCursorSample so exceeding MAX_CURSOR_SAMPLES
evicts the oldest sample whose interactionType is not "manual-zoom", preserving
manual zoom markers in activeCursorSamples. Keep the existing capacity limit and
avoid removing a marker when no non-marker sample is available.

In `@src/components/video-editor/timeline/recordingZoomMarkers.ts`:
- Around line 49-51: Update the marker-region generation around overlapsExisting
and reserved so generated regions do not suppress later accepted shortcut
presses; distinguish pre-existing reserved spans from generated regions and end
each generated region at the next marker, allowing both 1200 ms and 1800 ms
presses to produce non-overlapping regions.
