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.
