v0.15.2

Documentation only. No code changes, no API changes.

The README and provider docs were recommending models that no longer exist. llama-3.3-70b-versatile was shown as the default, llama-3.1-8b-instant as the fast option, and mixtral-8x7b-32768 alongside them.

Mixtral was decommissioned on 20 March 2025, so that example had been failing for over a year. Both Llama models are decommissioned on 16 August 2026.

The docs now show MODEL_GPT_OSS_120B and MODEL_GPT_OSS_20B, which is what the provider already defaults to in code. The deprecated constants are unchanged and still shipped.
