v5.0.1: correct & safe (the first release)

Release of v5.0 "correct & safe": the checks of the plan's §8 pass, the ML report measures v4 against the fixed ML core, and a fresh install was walked through end to end. No code behaviour changed since 5.0-rc2.

Test result: 419 automated tests passed (python -m pytest), ruff clean. Fresh clone of 5.0-rc2 with a new venv from requirements.lock (pip check clean), a model exported through the web routes and a walk-through of every menu path; web trainer at 375 px in light and dark mode with 0 texts below WCAG AA (record). Every §8 check is mapped to its tests (audit). Windows 10 Enterprise LTSC 2021, Python 3.14.3, scikit-learn 1.8.0.

5.0.1: security patch, a dependency update only, no code change: certifi updated in requirements.lock. 419 tests passed, pip-audit clean, a real HTTPS request to the NVD API with the new CA bundle succeeded. Project version: 5.0.1.

Everything that changed, with the known limits: CHANGELOG.

An older version, kept for the record: the latest is v5.4.
