_analyzer.py 388 -> 226. The file walk, dotted-name map, import
resolution and fingerprint go to _deps.py; the skip frozensets and the
function regex to _scan_tables.py, which covered the last nine lines
after the first cut landed at 259.
_is_binary is the only name any test patches on _analyzer and it stays
put, so no patch string needed editing. Only test_analyzer.py's import
block had to be split.
Pass count is 216 before and after.

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.
