"""Harden hwfit model-catalog parsing against non-string field values.

`params_b` and `is_prequantized` read free-form fields straight off the HF
catalog JSON. `parameter_count` is normally a string like "7B" and
`quantization` a string like "FP8", but a catalog row can carry a non-string
(e.g. an integer parameter_count, or a null/number quantization). The code
called `pc.strip()` / `q.startswith(...)` directly, so one such row raised
AttributeError and aborted the whole ranking pass (params_b/is_prequantized
run for every model). Non-strings are now treated as unknown.
