New python_pkg/code_tutor package that turns an unfamiliar codebase into an interactive lesson: analyse code into items (_analyzer), order them dependency-first (_plan_builder), pose reimplement challenges (_challenge + _challenge_support), verify user implementations with tests and coverage (_verifier), track progress (_progress/_session), and offer local-LLM hints (_llm), driven by a Typer/Rich CLI (cli). - meta/pyproject.toml + .pre-commit-config.yaml + meta/requirements.txt: add anthropic/rich/typer deps, a cli.py per-file-ignore (Typer B008 etc), and code_tutor-specific ruff/pylint/mypy tuning. - _challenge.py and its tests are split across _challenge_support.py and test_challenge_part2/part3.py to stay under the 500-line file cap. Verification: pytest 631 passed at 100% line+branch coverage; every file <=500 lines; pre-commit (ruff ALL, mypy strict, pylint 10/10, bandit, evidence + multi-file contract) green.
