## Summary by CodeRabbit

* **New Features**
* Start/stop system or meeting recordings with Ogg/Opus artifacts and
native start/stop APIs; workspace backup recovery.

* **Refactor**
* Simplified recording lifecycle and UI flows; native runtime now
orchestrates recording/processing and reporting.

* **Bug Fixes**
* Stronger path validation, safer import/export dialogs, consistent
error handling/logging, and retry-safe recording processing.

* **Chores**
* Added cross-platform native audio capture and Ogg/Opus encoding
support.

* **Tests**
* New unit, integration, and e2e tests for recording, path guards,
dialogs, and workspace recovery.
