- Implement native bridge for Windows cursor capture via PowerShell/C#
- Add cursor-free capture using getDisplayMedia with setDisplayMediaRequestHandler
- Update video player and exporters to support native cursor telemetry
- Enable system audio capture on Windows via WASAPI loopback
- Add interpolation for smoother cursor movement in playback and export
- Improve cursor scaling and visibility handling in editor and playback
discardLatestPending() popped whichever batch happened to be at the
back of the queue. With a Stop → Record → Discard sequence, the
pending queue can have recording B's batch sitting in front of A's by
the time A's finalize callback resolves (because finalizeRecording
awaits fixWebmDuration), so the discard targets the wrong recording.
Tag each completed batch with the recording id supplied at
startSession() time and replace discardLatestPending() with
discardBatch(recordingId). takeNextBatch() now returns the full
{recordingId, samples} shape so prependBatch() can re-queue it on
write-failure without losing the id. The renderer already owns a
stable recordingId (Date.now() in useScreenRecorder) and the IPC
surface threads it through set-recording-state and
discard-cursor-telemetry.
Adds a regression test that mirrors FabLrc's scenario in PR #457:
two recordings finalize, A is discarded after B has already been
queued, and the buffer must drop A while keeping B intact.
Address two issues raised during review:
P1 – When a recording is cancelled or restarted, setRecordingState(false)
enqueues its cursor batch but store-recorded-session is never called,
leaving a stale batch that contaminates the next recording's telemetry.
Add discardLatestPending() to the buffer and a discard-cursor-telemetry
IPC handler; the renderer now calls it on the discard path.
P2 – takeNextBatch() dequeued the batch before fs.writeFile, so a write
failure would permanently lose the telemetry. Wrap the write in
try/catch and re-insert the batch via prependBatch() on failure.

- Add useCameraDevices hook to enumerate video input devices
- Update useScreenRecorder to support webcamDeviceId selection
- Add device selector UI above HUD bar (mic + webcam, hover-to-expand)
- All selectors and HUD bar are absolute-positioned to prevent layout shifts
- Increase HUD window to 600x200px to accommodate device panels
- Add unit tests for useCameraDevices hook
