generate_all_docs.sh now runs check_frozen_docstrings.sh as a hard gate after
doc generation: the frozen (non-3D) binding surface must stay 100% MCRF_*
macro compliant, or the doc build fails. This is the docstring analog of the
API-surface snapshot test -- it prevents future raw docstrings from silently
regressing the frozen 1.0 documentation contract. Skipped gracefully when
.venv-audit is absent; experimental src/3d/ bindings remain exempt.
