GitHub is canonical for aldabra now (per 2026-05-10 architecture call —
Gitea is a pull-mirror cache, not a forge we publish to). Build process
fetches pallas direct from github.com, no rewrite needed.
- Dockerfile: drop the `--mount=type=secret` git_credentials dance + the
url.insteadOf rewrite. cargo fetches pallas straight from
github.com/Sulkta-Coop/pallas at the locked SHA. No secret needed.
- docs/internal-build-rewrites.md: removed. The rewrite was the entire
reason for the doc, and the rewrite is gone.
Internal builds (Lucy / crafting-table / dev hosts) still hit
github.com for pallas, same as external builds. One extra WAN hop per
crate, but consistent everywhere and no environment-specific config.
