Summary of Changes

• Targeted selector subscriptions: Replaced coarse global \lowChatStore.subscribe(notify)\ invocations across core consumers with fine-grained \subscribeSelector\ hooks:
  • \useSessionTerminalDirectory: Now only triggers notifications when the evaluated \�ctiveSessionTerminalDirectory(workspaceId)\ result changes, instead of on every token streaming chunk in any session.
  • \useActiveSessionState: Only wakes up when the active session entity reference or the specific scoped session changes in the store, and filters global state machine broadcasts to only the active session.
  • \useSessionTabLabels: Selects on \state.sessions\ Map identity rather than waking on unrelated flow store mutations.
  • \ContentCanvas\ and \AuxPane: Directly select \s => s.activeSessionId\ to eliminate re-rendering when background sessions update or stream.
