[BUG]: codestral, pixtral, mixtral skip Mistral tool call transform (has fix)

[tobwen]

Description

When using codestral, pixtral, or mixtral via a custom @ai-sdk/openai-compatible endpoint, tool call IDs are not normalized to Mistral's required 9-character alphanumeric format, causing API errors. PR #2440 added this for @ai-sdk/mistral and devstral but missed these three.

Plugins

none

OpenCode version

v1.2.21, dev

Steps to reproduce

1. Configure a custom provider in opencode.json using @ai-sdk/openai-compatible with a model ID containing codestral, pixtral, or mixtral
2. Start a session and trigger a tool call
3. Observe API error due to invalid tool call ID format
