fix: use directory-aware client for delete, rename, command, permissions, questions

- sessions.ts: deleteSession looks up session.directory and uses clientFor()
  instead of bare client, so cross-project deletes hit the right server path
- index.tsx: submitRename uses clientForDirectory(session.directory) so renames
  work for sessions not owned by the active project directory
- index.tsx: handleSwitchDirectory calls catalog.load() after a directory switch
  so agents/commands/providers refresh for the new project
- session/[id].tsx: introduce sessionClient (directory-aware) and use it in
  handlePermissionReply, handleQuestionReply, handleQuestionReject, slash-command
  send, and the refreshPending bootstrap call; also add 'directory' to useEffect deps
- catalog.ts: remove debug console.log

app/(tabs)/index.tsx
