Adopt shared Scala CI workflow

[stasimus]

Replaces the hand-written ci.yml with a call to the shared workflow, so tests, coverage, binary compatibility, formatting and scaladoc are configured centrally.

Checks now run as explicit sbt tasks rather than through the check alias, and checkout is unshallow so versionPolicyCheck has a previous version to compare against.
