Fix all ESLint errors

- Remove unused imports and variables
- Replace 'any' types with proper type guards
- Add comments to empty catch blocks
- Fix Response/Request type imports in logger
- Use 'unknown' instead of 'any' for generic types
- Remove unused createMcpServer and setSessionOwner imports

All ESLint checks now pass.
