Add get_hookconfig method to HookimplMarker for type-safe config extraction

- Add HookimplMarker.get_hookconfig() method that returns HookimplConfiguration directly
- Update test files to use new method instead of accessing dynamic attributes
- Fix mypy type errors in test_multicall.py and test_hookcaller.py
- Update CLAUDE.md to use 'uv run mypy src/' command
