fix(cortex-tui): implement missing commands and improve error display (#217)

- Implement handlers for /agents, /commands, /init, /share commands
- Show unimplemented command errors as warning toasts (orange, no emoji)
  instead of system messages for better visibility
- Add cortex-commands dependency to cortex-tui for builtin command access

Commands implemented:
- /agents - lists all custom agents (project and global)
- /commands - lists all custom commands
- /init [--force] - creates AGENTS.md in project directory
- /share [duration] - generates share link for current session
