@adhd/apigen-plugin-api-express

apigen target plugin (--type api-express) — exposes a source file's exports as an Express HTTP API. One POST /<namespace>/<fn> route per export (handlers call res.json(result)). Generates routes.ts to disk and runs a live server.

Part of apigen. Driven via @adhd/apigen-cli.
