Subject: [PATCH] feat(models): add MiniMax-M3 to native minimax providers + 1M
 context (#36214)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add MiniMax-M3 to the minimax, minimax-oauth, and minimax-cn curated
lists (these are hardcoded — the native Anthropic-format endpoint has no
/v1/models listing and the providers aren't in _MODELS_DEV_PREFERRED, so
new models don't auto-pull). Add a DEFAULT_CONTEXT_LENGTHS key
'minimax-m3' -> 1,000,000 so M3 resolves to its 1M context on every
surface (native ID + OpenRouter/Nous slug) via longest-key-first
substring match, while the M2.x series stays at 204,800.
