chore(plugins): sync generated content mirrors

Regenerates `plugins/*/skills`, `plugins/*/agents`, both per-plugin `plugin.json` manifests and the
two marketplace mirrors from `.apm/` per ADR-0017, via `scripts/sync-plugin-content.sh --all`.

The manifests matter beyond tidiness here: `plugin.json` carries the plugin version and wins over
the marketplace entry at install time (calculatePluginVersion precedence). Until this ran, the patch
bumps in the preceding commit were inert for anyone installing these plugins.

 Before any tool call, extract `owner` and `repo` from the git remote (skip this if an orchestrating caller already passed them in):
 
 ```bash
-git remote get-url origin
+rtk git remote get-url origin
 ```
 
 If origin is not set or the URL is not a Gitea URL, stop and report: "No Gitea remote found — set origin to your Gitea instance URL."
