Added os.Logger-based logging (subsystem: com.xorbitlab.bugger) covering:
- FeishuAuthService.send(): raw HTTP request URL, method, body, auth header,
response status code, and raw response body (up to 1000 chars)
- exchangeCode(): before/after token exchange with token previews
- TokenManager.handleCallback(): each step with success/failure
- LocalOAuthServer: server start, connection received, code extracted
View logs in: Xcode debug console, or Console.app → filter 'bugger'
Also fixed type inference ambiguity in generic send<T>() calls.
