[repo] Smoke tests in CI

### Description

Library is delivered in different packages and used in different setups. We should have a CI workflow which verifies that library has no issues.
What should be checked:
- examples are compiled and runnable
- library has all classes in `shaded` and `all` packages.

Start by locating the repository's existing CI workflows, example projects, and package build configuration. Verify how examples can be compiled and run, then inspect how the shaded and all packages are produced; done means CI checks both runnable examples and class coverage in those packages.
