feat: Add raw output logging and endpoint for debugging

- Introduced a new environment variable `AUTOMAKER_DEBUG_RAW_OUTPUT` to enable raw output logging for agent streams.
- Added a new endpoint `/raw-output` to retrieve raw JSONL output for debugging purposes.
- Implemented functionality in `AutoModeService` to log raw output events and save them to `raw-output.jsonl`.
- Enhanced `FeatureLoader` to provide access to raw output files.
- Updated UI components to clean fragmented streaming text for better log parsing.
