Fastify plugin shape

If it doesn't hold up in production, it doesn't make the cut.

I publish Fastify plugins (fastify-orama, fastify-at-mysql, lyra-impact). The shape below is what every one of mine looks like. It's small, it's deliberate, and it doesn't drift between repos.

When this skill is active

You are about to:

• Write a new Fastify plugin (in-repo or standalone package)
• Add a fastify.decorate(...) call
• Configure or modify a fastify-plugin (fp) wrapper
• Add a TypeScript module augmentation (declare module 'fastify' {})
• Validate plugin options or decide what to expose
