Automate Release Verification Pipeline

### What

Establish automated CI workflows that verify and execute the Time module release
pipeline end-to-end:

1. **Automated release workflow** — a `release.yml` triggered via
`workflow_dispatch` that builds Linux + QNX, collects the coverage artifact,
and creates a draft GitHub Release with a filled changelog template.
Based on the pattern from `eclipse-score/lifecycle`.

2. **Reference integration verification** — a CI workflow that triggers a smoke
test in the [SCORE Reference Integration](https://github.com/eclipse-score/reference_integration)
to confirm the Time module works correctly in the full ecosystem after each
PR. Based on the pattern from `eclipse-score/lifecycle` (`reference-integration.yml`).
