fix: update codex to 0.166.0 - #734

…profile modes, Codex 0.166

Merges agentclientprotocol/codex-acp agentclientprotocol#727, agentclientprotocol#395, agentclientprotocol#728, agentclientprotocol#731, agentclientprotocol#733, agentclientprotocol#734 and agentclientprotocol#609.

- Permission profiles follow upstream agentclientprotocol#395: profiles are listed when a session
  opens and offered as `permission-profile:<id>` modes. The fork keeps its
  custom-permissions mode, restoring the thread's own permissions, and applies
  a mode change to the thread immediately.
- An unknown INITIAL_AGENT_MODE still fails instead of falling back.
- `_session/rename` and `_codex/session_rename` share the standard
  `session/set_title` path.
- Provider updates restart the app-server when its startup routing changed,
  even with no open session.
- Real Codex fixtures honor CODEX_PATH.
- Generated app-server types stay on the fork's experimental generation.
