## Summary by CodeRabbit

## Release Notes

* **Refactor**
* Reworked real-time backend wiring to centralize workspace, comments,
and Copilot embedding handlers under a unified server setup.
* Updated Copilot embedding real-time handling to use context
configuration when publishing updates.
* **New Features**
* Added automatic startup validation to ensure all required real-time
request/topic handlers are registered (for applicable server flavors).
* **Bug Fixes**
* Workspace real-time access now determines team status from quota
state.
* Improved Copilot embedding progress publishing (including completion
events).
* **Tests**
* Expanded real-time registry completeness and Copilot embedding
provider coverage.
  * Added quota-state restoration coverage after clearing stale expiry.
