Unblock Jenkins pipelines and builds — stuck queues, executor starvation, failing stages — with evidence from the build and the triggering change.

AgentOffline
A Jenkins agent shows offline and will not connect. Separate transport, secret, JDK, host, label, and cloud causes — then diagnose and fix each.
BuildFailure
A Jenkins build that fails at a stage needs the right log, not the whole console. Find the failing stage, tell FAILURE from UNSTABLE, and trace the change.
ExecutorStarvation
Jobs sit in the queue waiting for an executor. Separate true starvation from label mismatch, blocked builds, throttling, and flyweight waits — then clear it.
