fix(ci): bind test server to 127.0.0.1 and make releases on-demand

- geomark CLI tests: explicit 127.0.0.1 binding fixes IPv6 mismatch
  on Node 18 in GitHub Actions (server listened on 0.0.0.0 but CLI
  connected via localhost which resolved to ::1)
- auto-release: remove push trigger, keep workflow_dispatch only —
  releases are now manual via Actions UI
