Fix CI tests and speed up integration tests

- Speed up simulation 10x for integration tests (reduces test time from
  10+ minutes to ~2.5 minutes)
- Add small delays between TCP commands in tests for reliability
- Fix Gitea CI release job (use gitea.ref instead of github.ref)
- Revert write() error-check that was consuming query responses
