ReadConsole: lock Debug.Log classification to Log; avoid bit-based fallback when stacktrace shows Debug:Log

- Detect explicit Debug.Log in stacktrace (UnityEngine.Debug:Log)
- Do not downgrade/upgrade to Warning via mode bits for editor-originated logs
- Keeps informational setup lines (e.g., MCP registration, bridge start) as Log
