* Cookbook fit: consumer-AMD GGUF recommendations + accurate estimates (core logic)
Split of #746 — the estimate/ranking MATH only, so it can be reviewed with tests
first (UI changes follow separately). Backend files only: no static/js here.
services/hwfit/fit.py, services/hwfit/hardware.py:
- Recommend GGUF/llama.cpp on consumer AMD (RDNA, gfx10/11/12) instead of
formats that don't run on consumer Radeon — vLLM-only AWQ/GPTQ/FP8 AND
vendor-specific NVFP4 (NVIDIA) / MLX (Apple). Datacenter Instinct (CDNA) and
CUDA are left untouched.
- More accurate speed estimates across more GPUs (adds RDNA bandwidth data).
- Detect AMD/RDNA GPUs (gpu_family from rocminfo) so fit/serve can branch on it.
tests/test_hwfit_amd.py: AMD recommendation path, quant/bit matching, estimate
realism, gfx RDNA-vs-CDNA classification.
Rebased onto current main (analyze_model gained a scoring_use_case param there;
kept it). Vision detection intentionally NOT added here — main already ships a
"Vision" type filter + multimodal use-case handling; duplicating it was dropped.
Checks: py_compile clean; pytest tests/test_hwfit_amd.py + hwfit/serve suites
= 28 passed; full suite 0 new failures vs main.

* Tests: assert NVFP4/MLX/FP8 formats are filtered on consumer RDNA
Backs the #972 claim with an explicit regression: no NVIDIA NVFP4, Apple MLX,
or vLLM-only FP8/AWQ/GPTQ repos are recommended on a consumer Radeon, and guards
against vacuity by asserting such repos exist in the catalog.
