rlx-mistral 0.2.5

Mistral 3+ / Ministral runner — STUB (PLAN.md M4)
Documentation

Mistral 3+ / Ministral runner.

Mistral 3 / 3.5 / 4 and Ministral 3 ship as general.architecture = mistral3 or mistral4 in their GGUF converters — Llama-shaped with per-arch deltas. This crate is a thin wrapper over [rlx_llama32::Llama32Runner] with arch validation.

Caveat: The underlying rlx-llama32 builder doesn't yet apply Mistral 3's per-layer sliding-window mask or Mistral-specific RoPE base — runs will produce some tokens but won't match the upstream reference until those land in rlx-llama32. PLAN.md M4 follow-up.
