Why:
Daily stable packages need durable multi-version retention without using
GitHub Pages as an ever-growing package store.
Impact:
Debian 13 amd64 package builds can publish to a future Spaces archive.
Before/After:
Before, staging replaced a Pages repository. After, Actions maintains an
append-only signed APT archive with at least five years of retained builds.
Technical Overview:
Build and verify Debian 13 packages in Actions, incrementally merge signed
APT indexes, and publish immutable packages and snapshots to an S3-compatible
archive. Scheduled publishing stays disabled until DigitalOcean is ready.
