chore: cut GitHub, make vrcx Gitea-only

- relink README/CHANGELOG/pyproject to git.engelgardt23.ru; drop github build badge
- update-check + clone URL point to Gitea; rename GITHUB_REPO -> REPO
- port CI to .gitea/workflows (self-contained, publishes Gitea release)
- remove .github (workflow + issue templates)
