Issue for this PR

Closes #27519

Type of change

  • Bug fix
  • New feature
  • Refactor / code improvement
  • Documentation

What does this PR do?

This PR adds a missing overflow pattern to prevent infinite retry loops when OpenAI-compatible providers return context overflow errors.

Some OpenAI-compatible providers return "tokens in request more than max tokens allowed" when the context window is exceeded. This pattern wasn't recognized in the OVERFLOW_PATTERNS array, causing the system to infinitely retry instead of triggering context compaction.

The fix adds the pattern /tokens in request more than max tokens allowed/i to the OVERFLOW_PATTERNS array in packages/opencode/src/provider/error.ts.

How did you verify your code works?

Add missing context overflow pattern for OpenAI-compatible providers
07b62c5 
Fixes anomalyco#27519

Some OpenAI-compatible providers return the error message "tokens in request more than max tokens allowed" when the context window is exceeded. This pattern was not recognized by the overflow detection logic, causing the system to retry indefinitely instead of triggering context compaction.

This adds the missing pattern to OVERFLOW_PATTERNS to ensure proper handling of this error across all OpenAI-compatible providers.
