artifact_inventory(api) enumerates a repo's servable artifacts WITHOUT
gating on format — a GGUF-only repo is a first-class bring (design §2b-1/2;
select_weight_files stays the vLLM/safetensors gate). GGUF variants are
enumerated at any depth, grouped by quant token with multi-part files
summed, mmproj projectors split out (never a variant); safetensors sets
reuse the adapter-excluding filter; cardData.base_model rides along
(friction #11 — lineage for ⑤'s taxonomy + credits). inspect_repo() wraps
the API fetch with structured errors; CLI: deriver.py --inventory <repo>
--json (the c3 Bring pane's INSPECT subprocess). Offline guard test.
