- Update GetResult struct to use MappingsData union instead of extracting .list
- Add generated() method to MappingsData that returns empty array for compact format
- Fix toMapping to properly branch between coverage (full format) and non-coverage (compact)
- Remove pointless variable discards that caused compilation errors
- Error reporting now uses compact format and does on-demand VLQ decoding via find()
This ensures compact sourcemaps are only expanded to full format when coverage
analysis is enabled, providing memory savings for normal error reporting scenarios.
