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.
