"""Standalone CLI wrapper around :mod:`crewai_devtools.docs_versioning`.

``devtools release`` calls the same freeze logic during its docs PR step; this
script is the manual escape hatch for one-off freezes (e.g. retroactively
freezing a forgotten release, or freezing without going through the full
release flow).

Usage::

    python scripts/docs/freeze_current_edge.py 1.15.0

Idempotent: re-running with the same version is a no-op (existing snapshot
directory and existing docs.json entry are both detected).
