Rewrites python_pkg.wake_alarm imports to wake_alarm, vendors the shared configure_logging helper, drops the monorepo PYTHONPATH from install.sh and the systemd unit (package is now pip-installed), and untracks wake_state.json (runtime HMAC state, now gitignored). Scaffolds standalone lint/test config copied from the already-corrected diet_guard scaffold (pylint --fail-under=10 with tests excluded and the use-implicit-booleaness/consider-using-with disables, mypy's actual disabled-error-code set, ruff ALL, bandit, 100% branch coverage), plus the wave.Wave_write generated-members fix this package's _audio.py needs.
