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.

+# Resolving a bare issue-or-PR number
+
+The user has referenced a bare number without saying "issue" or "PR" (e.g. "what's going on with #42"). Resolve it with a real call — never dispatch to `gitea-issues` or `gitea-prs` by guessing from phrasing alone, because "that sounds like a bug" is not evidence and the two domains share one number space.
+
+1. Invoke `gitea-issues` to run `issue_read method: "get"` on that number.
+2. Check the response's `is_pull` field:
+   - `true` → it's a PR. Invoke `gitea-prs` for full PR detail (status, diff, reviews as appropriate to the request) and present that instead.
+   - `false` or absent → it's an issue. Present the issue detail already retrieved.
+3. If the resolution call 404s, don't conclude the number doesn't exist. Gitea hides permission errors as not-found (documented in `gitea-issues`' Gotchas), so report the 404 and suggest verifying the token carries `write:issue` rather than reporting "no such issue or PR."
+
+Then report per `SKILL.md`'s Report section, saying which domain the number turned out to be before showing detail ("That's a pull request:" / "That's an issue:") — otherwise the user cannot tell the resolution happened.
