OpenLoomi Setup (end-to-end wizard)

The bridge now exposes a single end-to-end wizard: setup --yes. One invocation walks the full Codex state machine:

install OpenLoomi.app from the official GitHub release
  → set OPENLOOMI_AGENT_PROVIDER=codex in the GUI launchd / environment.d
     (auto-restarts the desktop if it was already running)
  → launch the desktop app (`open -a <desktopMarker>` / platform equivalent)
  → wait for the local HTTP API to come up on http://localhost:3414
  → mint a guest bearer (one-tap sign-in) into ~/.openloomi/token
  → { ready: true }

Each transition is automatic. Do not ask the user to click anything in the GUI. The bridge only surfaces a stop condition when the next step truly requires human action, e.g. AI provider not configured, or the native Codex runtime isn't reachable.

This wizard is the Codex-side equivalent of Claude's /openloomi:setup. Both plugins speak the same bridge commands, the same flag names, and the same stop-condition vocabulary so an install step that works on one works on the other.

Quick workflow

1. Make sure the Codex sandbox is set to a mode that allows the wizard to actually run. setup needs to write to /Applications (macOS) or ~/.config/environment.d/ (Linux), install/launch the desktop helper, and reach http://localhost:3414. workspace-write is the minimum that usually works; danger-full-access is the safe choice for the first run. If you do not have approval, ask the user before invoking the bridge.
2. If the bridge returns setup: install_attempted (only happens on the very first invocation when --yes is required), this is informational, --yes is already passed through and the wizard proceeds.
3. Run:
