Pull request overview
This PR introduces integration-test sharding to speed up CI by splitting the integration suite into isolated Docker Compose projects, plus adds supporting tooling (log capture, shard coverage guard) and updates workflows/actions accordingly.
Changes:
- Add shard-aware integration test execution (Makefile shards +
TEST_PATTERNforwarding) and a shard coverage guard for CI. - Introduce a Compose runner script that captures run output + node log + service logs per shard into dedicated artifacts.
- Replace the GitHub license-header action with a repo-local license header verification script; update CI workflows and housekeeping.
