chore(infra): add CI workflow and fix release engineering (#42)

* chore(infra): add CI workflow, track lockfile, fix release engineering

* fix(ci): use --legacy-peer-deps for unresolvable peer dependency

* fix(ci): checkout Core repo for test imports

Tests import ../../NoJS/src/index.js which doesn't exist in CI.
Add a checkout step for ErickXavier/no-js at ../NoJS so the
relative path resolves correctly from the test files.

* fix(ci): use git clone for Core repo (actions/checkout path restriction)
