_check_skill_version advised "Run 'graphify install' to update" on ANY
version mismatch. But `install` writes the package's OWN bundled skill and
re-stamps .graphify_version, so when the skill on disk is NEWER than the
running package, following that advice silently DOWNGRADES the skill to
silence the warning. The docstring even said "warn if the skill is from an
OLDER version" but the code never checked direction.
Compare versions numerically (new _version_tuple, so 0.10 > 0.9 and a
malformed stamp degrades instead of raising). When the skill is newer than
the package, recommend upgrading the package (uv tool upgrade / pip install
-U) instead of install; the older-skill case is unchanged. Hit in practice
by a stale `uv tool` CLI and by contributors whose dev checkout stamped a
newer skill. Reported by @TPAteeq.
4 tests (numeric ordering, both mismatch directions, silent-when-equal).
Full suite 2730 passed.
