fix: follow symlinks in model discovery, update model catalog

- Add -L flag to find in benchmark scripts (follows symlinks to /data/models/llms/)
- Exclude mmproj-*.gguf (vision projection files, not LLM models)
- Update configs/models.conf: remove Qwen3-Coder (user prefers Qwen3.5-35B-A3B),
  add Qwen3.5-27B-Q4_K_M and Q8_0 variant, reflect actual downloaded models
