- Add .catch(...) to telemetry.cleanupOldFiles fire-and-forget for consistency with backup.runDaily pattern (M1 from T10 code review). - Mark Roadmap §3 #7 as completed (✓). - Correct spec: tray:exportTelemetry was never an IPC channel — tray callbacks run in main process directly. Replace with "트레이 콜백 (main 내부)". Closes v0.2.3 task 1 of 7. Next task: #4 휴지통 (migration v3). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
