fix(typing): resolve all pyright type checking errors

- Add explicit type annotations for staticfile path variables
- Make _get_platform_info() public as get_platform_info()
- Remove unused functions _setup_tailwind_environment and _create_standard_config
- Add type annotations for template directory variables
- Fix unused variable in test_error_scenarios.py
- Configure pyright to treat private member access as warnings in tests
- Add pyright hook to pre-commit configuration
- Update CLAUDE.md with changelog requirements for future commits
