chore(gitea): regenerate the flat content mirror after the ADR-0020 retrofit

Generated output, not authored content: scripts/sync-plugin-content.sh --all.
Claude Code has no .apm/ awareness, so this compiled mirror must track .apm/ or
the check-plugin-content-sync pre-push hook reports drift.

Deferred to a single commit at the end of the wave on purpose. sync_dir runs
rm -rf before every copy, so running it while seven agents were editing the
same plugin would have raced them; agents were told not to sync for that reason.
