[Release] v1.4.0 (#436)

- Bump RubyUI::VERSION to 1.4.0 and regenerate both lockfiles
- Update home hero badge to "Native Dialog, Form docs, and more"
  (header version badge reads RubyUI::VERSION, updates automatically)
- Rebuild MCP registry for 1.4.0

Highlights since v1.3.0: native <dialog> element (#435), accordion
closed-content visibility fix (#433), Form Rails-integration docs (#434),
multi-component generator and as:-render options.
