ci: optimize GitHub Actions to run unit tests only

- Switch from test:ci-safe to test:unit:ci for faster pipeline
- Add memory optimization with NODE_OPTIONS
- Reduce coverage threshold to 70% for unit tests
- Disable integration tests in CI (can be run manually)
- Add cli-fixes branch to trigger list
- Update unit test coverage job configuration

This significantly reduces CI pipeline execution time while
maintaining quality gates through unit tests.
