FN-5844: add plugin dev loop and external authoring docs
Add a local plugin development loop plus publishable external plugin guidance.
- add `fn plugin dev` routing and implementation with supervised build, install, and hot-reload behavior
- export plugin loader/store helpers and add CLI tests for dev flow, pack shape validation, and scaffold docs coverage
- document external plugin authoring, update CLI/plugin authoring docs, and add a patch changeset for `@runfusion/fusion`
