feat(minimax-portal-auth): add regional endpoint selection and improve OAuth flow

- Support Global (api.minimax.io) and CN (api.minimaxi.com) endpoints
- Add endpoint selection prompt in onboard flow
- Add notification_message display after successful login
- Update documentation with Coding Plan details
- Fix API response field parsing (expired_in, base_resp.status_msg)
- Add debug logging for OAuth response and poll results

 ## Choose a setup
 
-### MiniMax M2.1 — recommended
+### MiniMax OAuth (Coding Plan) — recommended
+
+**Best for:** quick setup with MiniMax Coding Plan via OAuth, no API key required.
+
+Enable the bundled OAuth plugin and authenticate:
+
+```bash
+moltbot plugins enable minimax-portal-auth
+moltbot gateway restart
+moltbot onboard --auth-choice minimax-portal
+```
+You will be prompted to select an endpoint:
+- **Global** - International users (`api.minimax.io`)
+- **CN** - Users in China (`api.minimaxi.com`)

+See [MiniMax OAuth plugin README](https://github.com/moltbot/moltbot/tree/main/extensions/minimax-portal-auth) for details.

 ## Configuration options
 
 - `models.providers.minimax.baseUrl`: prefer `https://api.minimax.io/anthropic` (Anthropic-compatible); `https://api.minimax.io/v1` is optional for OpenAI-compatible payloads.

-- MiniMax OAuth uses a device-code login flow.
-- Tokens auto-refresh; re-run login if refresh fails or access is revoked.
