GGUF: port v4's gguf_support.py (backend selection, content-based .gguf
detection, dequantize fallback) and wire it into both the diffusion-model
and CLIP loaders.
Pipeline editor: reopening the Models-and-pipeline settings window was
silently discarding the whole edited pipeline (a loaded preset, every
loader file, every sampler setting) because GET /api/pipeline is
deliberately stateless server-side and boot.js never fed its own
already-saved slots back into a freshly remounted editor -- found live
while walking through the MiniMax-H3 setup flow. Fixed by re-validating
the saved slots through check() on reopen instead of always replaying
the raw stateless default.
Also fixes, found via the extensive_testing adversarial loop over both
of the above: a stale file-listing cache in the pipeline window (no way
to see a newly-added model file without a full page reload), and a
chain of races/leaks in its own refresh/commit error-banner handling
that surfaced across five review rounds -- a rejection from a superseded
request overwriting a fresher success, a failure banner never clearing
on success, banners bleeding across groups on navigation, and a
commit()'s refusal landing on the wrong view after the user backs out
before it answers.
