v5.1.0

Added

• New-session page now offers "Extend CCC" integration-recipe cards (driven by kind: "extension" entries in static/templates.json): click a cookbook recipe — Annotate → UX-fixes queue, or bug-report widget → GitHub issues — to prefill the composer with a ready-to-run integration prompt for your own app's repo.
• Flow: "+ object" button creates empty object groups, group headers drag to reorder or nest in by-objects view, and an object-group name opens its Flow MD doc (CCC-92, CCC-93)
• Cookbook: Gmail hourly triage → iMessage alert recipe (CCC-101)
• Group chats: add-participant picker on chat rows and the reader header, plus "Join with this link" — paste a token into any session's composer to join (CCC-97, CCC-98)
• Files panel flips to a Queue view for UX-fixes worker sessions, and the server auto-nudges idle queue workers (CCC-100)

Changed

• New-session stage polish: chooser highlights the default path, centered and roomier prompt box, fun random project names; engine icon moved to the far right of conversation rows (CCC-87, CCC-94)

Fixed

• Fixes: Launch no longer forks a session a live headless process owns (CCC-96), load-earlier banner no longer auto-fires on open, repo chips track manual CWD edits (CCC-91), Files-panel Queue view scopes to the worker's project (CCC-99)
