Refresh Halo theme skill and starter

Reworks the `halo-theme-dev` skill around current Halo theme workflows: replaces bundled reference docs with on-demand documentation guidance, broadens the skill scope, removes the OpenAI-specific agent config, and adds eval coverage for settings, SEO, and Vite layout behavior. It also updates the Vite starter by pinning `vite-plugin-halo-theme`, adding a source `layout.html` contract plus `author.html`, wiring locale-aware `lang` handling, and adding ignored/generated asset placeholders for the build output.
