Why: two branches that both bump a skill 1.0.0 -> 1.0.1 with different
content merge without a conflict, and each passed the gate against its own
merge-base, so main could ship two changes under one version.
Implementation Notes:
- check-skill-version-bump requires the pushed version to exceed both the
merge-base and the main tip; failures name the baseline they missed.
- Presence is read from the tree, so a blob missing from a partial clone is
a read failure instead of a silently exempt "new" skill.
- A leading UTF-8 BOM no longer reads as a missing version.
- Version parts reject leading zeros in all three validators
(check-skill-version-bump, skill-size-check, factory-audit).
- New tests cover equal bumps, moved files, major/minor ordering, bad refs,
unreadable blobs, mode-only changes, symlinks and tag peeling.
Impact: ADR-0022 amended (reverses "not main's current tip"); gates.md
updated to match, including pre-commit 4.6.1's exact ref selection.
ADR: 0022

- Read changed paths NUL-delimited so non-ASCII paths are no longer
silently skipped.
- Fail closed when only local main resolves and the pushed commit is
the merge-base, instead of passing on an empty diff.
- Accept ASCII-only versions with at most nine digits per part.
- Check for python3/PyYAML up front, and report read failures as such
rather than as a missing version; name a missing SKILL.md.
- Document that pre-commit gates only the first ref of a multi-ref push.
Tests grow to 29 cases covering each fix plus annotated tags, CRLF
frontmatter, unrelated histories and pushing main.

check-skill-version-bump fails a push when a skill directory changed
against its merge-base with main (tests/ excluded) without a strictly
higher metadata.version than main. New, renamed and deleted skills are
exempt; every plugin is covered. Recorded as a dated section in
ADR-0022 and documented in gates.md.
Patch-bumps the 17 skills that changed on this branch without a bump,
so the branch passes its own gate. Simplification audit finding 33.
