v1.1.0 add /brief

/brief is now in the suite. Read related workspace markdown (cap 8), then do /brief <task> in the same turn. HTML only when the task is a specific page.

Also: /create-skill machine-path ban uses C:\Users\<user> so /publish-audit --platform github does not treat ellipsis placeholders as a real home path.

Pin: git clone --branch v1.1.0 https://github.com/napattan/agent-skills.git
