Release 5.0.2: strip -SNAPSHOT for Maven Central

Per docs/RELEASE.md step 1: strip -SNAPSHOT from pom.xml (5.0.2-SNAPSHOT ->
5.0.2) and bump the README release dependency examples from the previous
release (5.0.1) to 5.0.2. The snapshot dependency example stays at
5.0.2-SNAPSHOT.

Bundled with the b9555 llama.cpp bump on this branch so both land together
on merge. Tagging v5.0.2 to trigger the publish-release job is a manual
maintainer step.
