litellm wraps provider errors as ContextWindowExceededError: litellm.BadRequestError: Context Window exceeded for given call. No models have context window large enough for this call.
The phrase "context window exceeded" wasn't matched by the existing overflow patterns, so it fell through as a generic API error instead of triggering compaction.
This adds /context window exceeded/i to the shared matcher in provider-error.ts so litellm-wrapped errors are classified as context overflow, same approach as #35671 and #37840.
How did you verify your code works?
Built a standalone binary with ./packages/opencode/script/build.ts --single and ran it via packages/opencode/dist/opencode-darwin-arm64/bin/opencode. Pasted ~40k blocks into chat until the error appeared. The error still surfaces but compaction is now triggered automatically instead of leaving it as a dead-end API error.
