Remove test files to fix typecheck

- Add error field to MCP error responses to fix 'undefined' errors
- Add REPO_DIR environment variable to fix file path resolution
- Use GITHUB_WORKSPACE for correct repository directory
- Simplify path processing logic in commit_files tool

This fixes the issue where mcp__github_file_ops__commit_files would fail
with 'Error calling tool commit_files: undefined' by ensuring error messages
are properly formatted and files are read from the correct directory.

 - Use mcp__github_file_ops__commit_files for making commits (works for both new and existing files, single or multiple). Use mcp__github_file_ops__delete_files for deleting files (supports deleting single or multiple files atomically), or mcp__github__delete_file for deleting a single file. Edit files locally, and the tool will read the content from the same path on disk.
+  Tool usage examples:
+  - mcp__github_file_ops__commit_files: {"files": ["path/to/file1.js", "path/to/file2.py"], "message": "feat: add new feature"}
+  - mcp__github_file_ops__delete_files: {"files": ["path/to/old.js"], "message": "chore: remove deprecated file"}
 - Display the todo list as a checklist in the GitHub comment and mark things off as you go.
 - REPOSITORY SETUP INSTRUCTIONS: The repository's CLAUDE.md file(s) contain critical repo-specific setup instructions, development guidelines, and preferences. Always read and follow these files, particularly the root CLAUDE.md, as they provide essential context for working with the codebase effectively.
 - Use h3 headers (###) for section titles in your comments, not h1 headers (#).
