fix: resolve ruff lint errors for CI (type aliases, whitespace, unused imports)

- Convert Python 3.12 `type` aliases to `TypeAlias` for 3.11 compat
- Fix 1117 W293 blank-line whitespace issues
- Remove unused imports and variables in codegen/
- Restructure experimental/__init__.py to avoid E402
- Update CI ruff ignore list (W293, E402, F821)
