This release fixes the long-idle OAuth issue where users had to log in again and could see: 'invalid access token or token expired'.\n\n### Fixed\n- Resolved repeated re-login requirement after idle periods\n- Added credential loading from ~/.qwen/oauth_creds.json\n- Merged runtime auth and file credentials for robust refresh token recovery\n- Fetch now resolves a valid token dynamically per request\n- Added one-time retry path on 401/403 after cache reset\n\n### Impact\nUsers should now stay logged in across long idle intervals in normal OAuth flow, similar to official Qwen Code behavior.
