Daniel Han 0a3a8f5570 Route the real GGUF filename, keep non-GGUF curated models, key scoped downloads by file set
Five review findings, four of them ways a click did nothing or fetched
the wrong thing:

- A chat pick of a diffusion model routed ggufVariant (a label like
  Q4_K_M) in the search param the target page uses verbatim as the GGUF
  filename, so the load asked for a file that does not exist. Route
  ggufFilename; no filename means a curated non-GGUF pick, loaded as a
  pipeline.
- The task-scoped pickers kept only GGUF repos, so the catalog's bf16,
  bnb-4bit and single-file fp8 artifacts could not be discovered or
  downloaded on the Images and Video pages even though loadSpecFor
  knows how to load them. Keep curated artifacts whatever their format,
  in Recommended and in Hub search.
- Both pages deduplicated routed selections on the model alone, and
  they now stay mounted, so picking the same repo again -- another quant,
  or the same one after chat evicted it -- returned early without
  loading or clearing the query string. Key on model and quant.
- Every scoped image download shared one @diffusion job key regardless
  of the requested files, so switching quant mid-download adopted the
  running job: the UI waited on the first file set, then loaded a file
  that was never fetched. Include a digest of the file set in the key.
- A scoped plan silently dropped requested files missing from Hub
  metadata, and snapshot_download succeeds when an allow pattern matches
  nothing, so the job reported completion and triggered a load with
  required files absent. Fail the job instead.
