worker.js

/**
 * Cloudflare Worker — pool redirect for packages.omakasui.org
 *
 * apt always treats the Filename field in a Packages index as a path relative
 * to the repository base URL.  Binary packages live as release assets in
 * omakasui/build-apt-packages, so we need a redirect layer instead of storing
 * .deb files in this repository.
 *
 * Filename written to Packages:  pool/<tag>/<file>
 * Worker redirects:               /pool/<tag>/<file>
 *   → https://github.com/omakasui/build-apt-packages/releases/download/<tag>/<file>
 *
 * apt follows HTTP 302 redirects, so the download ends up at the GitHub CDN
 * without any binary ever being committed to this repo.
 *
 * Every other request is passed through to GitHub Pages unchanged.
