Subject: [PATCH] fix(model-requirements): align fallback models with available
 provider catalogs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- opencode/minimax-m2.7-highspeed → opencode/minimax-m2.5 (provider lacks m2.7 variants)
- opencode-go/minimax-m2.7-highspeed → opencode-go/minimax-m2.7 (provider lacks -highspeed)
- opencode/minimax-m2.7 → opencode/minimax-m2.5 (provider only has m2.5)
- added xai as alternative provider for grok-code-fast-1 (prevents wrong provider prefix)
