• Remote url source with full 40-char lowercase sha
• plugin-index.json regenerated (generate-plugin-index.py)
• Local validation: validate-catalog.py + generate-plugin-index.py --check

Note on pin SHA

Product freeze note 4b0edb6… was specified earlier; marketplace install requires a plugin package (plugin.json + skill), so the pin is the follow-up commit that adds those files on top of the reviewed product tree.

Test plan

• CI: catalog validation + plugin-index check
• Install from marketplace / source URL and confirm skill vesper-forge is listed
• Optional: run python3 server.py from the pinned tree and open http://127.0.0.1:7420/
