ci: add Gitea Actions workflow (.gitea/workflows)

- Primary workflow under .gitea/workflows (Gitea scans this before .github)
- Explicit https://github.com/... action refs for predictable resolution on Gitea
- Mirror under .github/workflows for GitHub Actions (short uses: names)

+# Gitea Actions — requires Gitea 1.19+ with Actions enabled and at least one act_runner
+# whose labels include the job's runs-on value (commonly ubuntu-latest). See:
+# https://docs.gitea.com/usage/actions/quickstart
+#
+# Explicit https://github.com/... action URLs work on all instances; short names also work
+# when the server fetches actions from GitHub (default) or from self with [actions].DEFAULT_ACTIONS_URL.
