fix: remove syntax errors from test files caused by sed

Fixed syntax errors in test files that were introduced by batch sed replacement:
- test_tools_with_schemas.py: Removed leftover broken comments and closing brace
- test_mcp_json_schema.py: Removed all instances of broken comment blocks

The sed command left remnants that broke Python syntax.
