## Modifications

Metadata wrap only — the upstream state-dict module names match the
LibreEC port byte-for-byte. The wrap adds `model_family`, `task`,
`supported_tasks`, `default_task`, `size`, `nc`, and `names` so the
unified `LibreYOLO()` factory routes without filename heuristics.

[LibreYOLO source repository](https://github.com/LibreYOLO/libreyolo).
