feat(provider): upgrade minimax preset to MiniMax-M3

Add MiniMax-M3 as the new default for the minimax provider preset and
remove deprecated M2.5/M2.1/M2 entries. MiniMax-M2.7 and the highspeed
variant are kept for users who pinned the previous generation.

Updated places:
- providerPresets.json: default models -> M3, modelContextWindows trimmed
- modelContextWindows.ts: built-in window list mirrors the new set
- provider-presets / providers-real / thinking tests updated to assert
  the new default
- .env.example and third-party docs (zh + en) recommend M3
- scripts/repro-issue-247-real.ts default model bumped to M3
