weichenandCursor c7eab1f7d1 fix(chat): add RWMutex to Session and snapshot accessors to close data race
- Session gains mu sync.RWMutex + SnapshotMessages/AppendMessage/
  TouchLastAccessed/SetProjectID/Project accessors
- sendMessageInternal, hydrateVisibleHistory, getOrCreateSession,
  cleanStaleSessionsLocked, handleChat, handleChatStream,
  enrichSessionWorkflowStage, bindSessionDocumentSummaryReader all use
  locked accessors instead of raw field access
- ProjectID mutation now goes through SetProjectID (only when changed),
  closing the cross-project pollution window in handleChat/handleChatStream
