Module header_cache 

Opt-in on-disk cache for parsed remote tensor-file headers.

inspect --cache-headers persists the parsed header — the same SafetensorsHeaderInfo every format (.safetensors / .gguf / .npz / .pth) normalizes into — keyed on (repo, revision, filename, etag), so repeat inspection of the same remote file across invocations (the natural pattern of iterative narrowing over a handful of quant candidates) is free on the second and third call.

Off by default: a plain remote inspect never touches local disk without this flag. Entries live under cache_layout::header_cache_path — an hf-fm-private sidecar directory alongside the standard hf-hub layout, not inside it — following the same precedent as the .hf-fm-snapshot.json sidecar in crate::cache.
