ci(cli): update workflow to use GoTestX and exclude cmd from coverage

- Renamed workflow to "CLI Build & Test" for clarity
- Added GoTestX installation step (go install github.com/entiqon/cli/cmd/[email protected])
- Updated coverage run to exclude cmd/ (avoids main.go dragging coverage down)
- Preserved coverage threshold enforcement at 80%
- Kept Codecov upload with token and flag set to cli
