/**
 * Build script for Bunny Edge deployment
 * Bundles edge script into a single deployable file
 * Secrets are read at runtime via Bunny's native environment variables
 *
 * The bundling pipeline is shared with `scripts/build-deploy.ts` via
 * `scripts/edge-bundle-lib.ts`; this script supplies only the Bunny-specific
 * bits: the entry point, the 10MB script-size ceiling, the source-map link
 * rename, and the `bunny-script.ts` + release-tag emission.
