Full Release Notes

## What's Changed

**Stateless extension tab sync** - TabsController pulls tab state on demand instead of long-lived ports, so the MV3 service worker stays stateless and survives idle kills without stalling the side panel.

**Tab status in agent context** - Tab summaries now include each tab's loading status for the LLM.
