"""Snapshot ModelFit Index scores for the current hardware.

Non-interactive and offline-safe: scores every catalog model against a real
hardware probe (no Ollama server or model downloads required — scores are
estimates unless a prior `auralynq-modelfit benchmark` run already recorded
measured tok/s for a model). Writes reports/modelfit_bench_report.json with
provenance. This is a read-only snapshot of `auralynq-modelfit recommend`'s
underlying scoring, not a new benchmark methodology.
