The three framework-free test mains under plugins/*/test were never run by
anything — not CI, not the plugin builds — and the velocity/paper/limbo jars
were only ever compiled by deploy/bootstrap.sh on a live host. CI gains a
'plugins' job (JDK 21 plus the Gradle 8.14 the plugin Dockerfiles pin) running
plugins/test.sh: the three mains (InviteCardTest's jars fetched from Maven
Central, pinned and digest-checked) and the three production builds.
The first real run surfaced and fixed two untested assumptions: InviteCardTest's
documented javac line omitted examination-api (adventure-api's Component
signatures reference Examinable, so javac needs it too), and limbo's '+' version
default cannot resolve — LOOHP's repository serves no maven-metadata — so the
script resolves the current release off the Limbo CI artifact name (the same
source bootstrap reads) and plugins/README.md stops advertising a bare
'gradle -p plugins/limbo build' that can never work.
Verified in gradle:8.14-jdk21 on the VM: mains OK (32/36/48 checks);
velocity/paper/limbo BUILD SUCCESSFUL.
