fix(opencode-provider): correct z.ai coding plan model mapping

[USerik]

The model mapping for 'z.ai coding plan' was incorrectly pointing to 'z-ai' instead of 'zai-coding-plan', which would cause model resolution failures when users selected the z.ai coding plan provider.

This fix ensures the correct model identifier is used for z.ai coding plan, aligning with the expected model naming convention.

apps/server/src/providers/opencode-provider.ts (1)

1038-1040: LGTM! Correct fix for the z.ai coding plan provider mapping.

The fix properly distinguishes between the base z.ai provider (mapped to z-ai) and the specific z.ai coding plan (now correctly mapped to zai-coding-plan). This ensures correct model resolution when users authenticate with the z.ai coding plan.

Code Review

This pull request correctly fixes a model mapping for 'z.ai coding plan' in the OpenCode provider, which was causing model resolution failures. The change is straightforward and addresses the issue described. My main feedback is to improve test coverage for the parseProvidersOutput method to prevent similar issues in the future.

[gemini-code-assist]

While this change correctly fixes the mapping, the parseProvidersOutput function lacks unit tests. To prevent regressions and ensure the robustness of provider parsing, I recommend adding tests for this logic in apps/server/tests/unit/providers/opencode-provider.test.ts. A test case could verify that 'z.ai coding plan' correctly maps to 'zai-coding-plan' and that other providers are also mapped as expected.
