MTPLX 1.0.1

A bug-fix release, hours after 1.0.0, because two things deserved fixing immediately.

Tuning finishes on every Mac

Some Macs could not complete the first-run tuning step: when the fan helper could not verify a max-fan ramp (a fresh machine without the helper's sudo grant, for example), tuning refused to run and setup stopped. Pinned fans make timing cleaner, but they were never worth a dead setup wizard.

Tuning now runs with fans on automatic when pinning is unavailable, says so in the results, and still saves only a depth that actually beats the baseline. If you want strict pinned-fan measurements for benchmarking, mtplx tune --require-max-fans keeps the old behavior.

Gemma 4 works from the CLI

The official Gemma 4 repos are assistant-pair bundles, and the CLI's Hugging Face preflight did not recognize the layout, so mtplx start refused models the app ran fine. The CLI now reaches the same verdict as the app.
