Subject: [PATCH] feat(nadia): Implement average function in src/calculator.py

Outcome: done
Changed: src/calculator.py:29-32
Verified by: `make verify` passed (16 tests, OK); `python3 -m compileall -q src/calculator.py` passed; manual assertion of all acceptance criteria passed
Findings: average(values: list[int | float]) -> float was added to src/calculator.py:29-32
Open: none
Confidence: high - all acceptance criteria met, header present, type annotations present, no comments/docstrings, compile passes, tests pass, manual verification confirms every criterion
