## Summary
- `vladopajic/go-test-coverage@v2` (v2.18.5+, released 2026-04-26/27) restructured its composite action to pass inputs via env-var mapping. Gitea `act_runner` doesn't expand `${{ }}` expressions inside docker-action `env:` blocks reliably, so the literal string `${{ inputs.config }}` reached the binary and broke the 'Check coverage' step.
- Replace the action with a direct `go install` + binary invocation (matching the established Frostmoln pattern).
- Use `--github-action-output` to expose `total-coverage` as a step output, replacing the manual `go tool cover -func | grep | awk` calculations.
- Baseline artifact now stores the percentage directly instead of the full coverage profile.
## Test plan
- [x] `prek run --all-files` passes
- [ ] CI passes on this PR
- [ ] After merge, baseline artifact format propagates on next push to main
Reviewed-on: #150
Add go-test-coverage for coverage threshold enforcement. Coverage data
is uploaded as artifacts on main branch and compared against baseline
in PRs using shell script that gracefully handles first run without
baseline. PR comments show coverage percentage.
