The GitHub org Molecule-AI was suspended on 2026-05-06; canonical SCM
is now Gitea at https://git.moleculesai.app/molecule-ai/. Stale
github.com/Molecule-AI/... URLs return 404 and break tooling that
clones / pip-installs / curls them.
This bundles all non-Go-module URL fixes for this repo into a single PR.
Go module path references (in *.go, go.mod, go.sum) are out of scope
here -- tracked separately under Task #140.
Token-auth clone URLs also flip ${GITHUB_TOKEN} -> ${GITEA_TOKEN} since
the GitHub token does not auth against Gitea.
