Paperclip Create Plugin

This walks you through the CLI-first workflow for building Paperclip plugins outside the core repo. It covers scaffolding with `paperclipai plugin init`, installing by local path, and the watch-rebuild loop where Paperclip auto-restarts your worker on file changes. The skill is opinionated about keeping plugins as separate packages and includes a verification checklist (typecheck, test, build) to run before you call it done. One thing to know upfront: the current runtime treats plugin code as trusted and same-origin, so there's no sandboxing yet. If you're adding custom functionality to a Paperclip instance or prototyping a connector, this gives you the exact commands and gotchas.
