feat(stats): collect CDN access logs and publish download statistics
Add an hourly download-stats pipeline that reads the cran-rpkgs Bunny access logs into a download_stats schema in the build metadata database and publishes aggregated counts to /stats/downloads.json for the rpkgs.com /stats page. - Classify each request (download, index, redirect reason, probe, noise) mirroring the edge router, and split cloud/CI networks from the rest. - De-duplicate downloads per client, package version and day, and key clients on a salted HMAC so no IP is stored or published. - Exclude our own CI runners and record run windows to show gaps. - Declare the zone's logging settings and allow CORS for JSON.
