Ivan Morgillo ac2c9ea3d6 Fix Claude Code install: ship marketplace manifest (#8) ...

The README told users to run 'claude plugin install github:hamen/material-3-skill',
which Claude Code rejects with 'not found in any configured marketplace' — that form
isn't supported, and the repo shipped only a plugin.json, not a marketplace manifest.

Mirror the proven compose_skill layout:
- Add root .claude-plugin/marketplace.json with a git-subdir source pointing at
  skills/material-3, so the repo is a valid plugin marketplace.
- Move the plugin manifest into skills/material-3/.claude-plugin/plugin.json.
- Document the working installs: 'npx skills add' and
  '/plugin add hamen/material-3-skill --subdir skills/material-3'.
- Update bin/ci and the plugin-layout test for the new layout.
