Fix pre-commit configuration and resolve all linting issues

- Replace problematic types-all with specific type packages
- Fix ruff linting errors (import order, unused variables, nested with statements)
- Fix mypy type errors with proper type annotations and ignore comments
- Fix exception handling with proper chaining (raise ... from e)
- Add type ignore comments for dynamic return types
- Clean up code formatting across all files
- All pre-commit hooks now pass successfully
