pstack-host

Host contract for pstack on VS Code and GitHub Copilot. Use whenever a pstack skill mentions Task, AskQuestion, subagent_type, /loop, Cursor model slugs, ~/.cursor, or a .cursor/ path, or when you need another pstack skill the skill tool cannot find. Maps those onto the agent tool, the host question tool, the wake script, Copilot paths, and ~/.copilot/pstack-models.md.
