fix: improve error messages for OpenAI-compatible providers

- Add specific guidance when OpenAI-compatible models fail to use tools
- Provide clearer instructions about XML tool format requirements
- Help users understand common issues with tool usage formatting
- Add tests for the new error message variations

Fixes #7226
