Merge dev into gitea/migrate-workflows (allow-unrelated-histories)

Merges the dev branch history into gitea/migrate-workflows to resolve
PR #24. The two branches had unrelated git histories due to the Gitea
migration. Conflict resolution favors gitea/migrate-workflows for
packages/, src/, .gitea/ structure and dev for apps/, .github/ content.
