chore(plugins): sync generated content mirrors

Regenerate plugins/*/skills/ from plugins/*/.apm/ after the previous
four commits, via scripts/sync-plugin-content.sh --all. The mirror is
generated output (ADR-0017) that check-plugin-content-sync's pre-push
hook diffs against .apm/; nothing here is hand-edited.

 Run `/skill-audit` on the resolved skill directory; resolve every FAIL before reporting done. It checks name-to-directory match, placeholders, both size budgets, boundary-target resolution and script hygiene — do not hand-check those. Hand-check the one thing it misses: an empty body reports `PASS  SKILL.md body word count 0 (ADR-0020 target: 600)`, so confirm at least one non-empty section exists.
 
-With `metadata.version` present, bump the **minor** version on create (new skills start at `0.1.0`) and the **patch** version on improve.
+Bump `metadata.version`: the **minor** version on create (new skills start at `0.1.0`) and the **patch** version on improve.
 
 **Commit verification.** Inside a git worktree: once the audit is clean, run `git add` and `git commit` — do not stop at staging. Re-run `git log --oneline -1` and confirm the hash changed from Step 1's. A non-empty `git diff --stat` is not proof: staged-but-uncommitted work is part of no commit and is silently lost if the tree is cleaned up. Report done only once the hash has changed. Outside a worktree (a skill under `~/.claude/skills/`, say) nothing is committable — report done on a clean audit, naming that as the reason.
