Subject: [PATCH] Bump junit-jupiter-engine to 6.1.2 and raise baseline to Java
 17

JUnit 6 requires Java 17+, so the dependabot bump to 6.1.2 (#265)
can't land without also raising the project's Java baseline from 11
to 17. Updates pom.xml compiler settings, CI workflow matrices, the
Nix dev shells, and README accordingly.

Supersedes #265.
