Update .claude-plugin/marketplace.json and plugin.json to v2.9.5 with
full metadata. Add plugin install instructions to README as the
recommended install method. The repo root serves as both the marketplace
and the plugin - skills/last30days/SKILL.md (symlink) is discovered
automatically.
Users can now install with:
/plugin marketplace add mvanhorn/last30days-skill
/plugin install last30days@last30days-skill
