Closes #415

Phase 5: enables check_untyped_defs = true and disallow_incomplete_defs = true under [tool.mypy]. The overrides block was already removed in Phase 4 (#470), so mypy skillware now runs with zero overrides.

Changes

Turning on disallow_incomplete_defs surfaced 42 no-untyped-def errors, all partially annotated signatures. Annotation only, no logic changes:

• console parameters (37): Console, or Optional[Console] = None where it defaults to None
• input_fn parameters (10): Optional[Callable[[str], str]]
• **kwargs in cmd_evm_dispatch, cmd_mail, cmd_addressbook_dispatch: **kwargs: Any
• _print_menu(menu): List[Tuple[str, str, str]]; cmd_interactive(parser): Optional[argparse.ArgumentParser]
• evm_config.get_web3: -> Any, since web3 is an optional dependency and may not be importable
• Matching typing imports; black reflowed a few long signatures

check_untyped_defs did not surface any additional errors.

Verification

• mypy skillware: Success, no issues in 25 files, no overrides
• black --check skillware / flake8 skillware: clean
• pytest tests/test_cli.py tests/test_evm_config.py: 156 passed
