ComfyUI plugin: integrated-mode bugs in GGUF detection, import guard and VRAM accounting

Confirmed from source (not run)

The SGLang ComfyUI plugin mis-detects non-H3 GGUF files, breaks an import guard and misaccounts VRAM.

What Badgr ran

Read python/sglang/multimodal_gen/apps/ComfyUI_SGLDiffusion on SGLang main. Not run: no ComfyUI or SGLang diffusion server was set up.

__init__.py catches ImportError and sets empty node mappings with only a comment, no log, so the nodes disappear silently (finding 4).
core/generator.py still has bare "return None" paths at lines 454 and 458 (finding 3).
The fix PR (#43536) is still open and unmerged.

Code reading only (not run): two of the four active findings were checked; the GGUF detection and registry findings were not.

Checked 2026-10-15 in Badgr’s local development environment.
