loadedIntoRunningServer

Hot-loaded into a running server (PlugMan et al) rather than booted with it — an UNSUPPORTED path, covered only because it is the one that breaks outright: onServerLoad is this host's sole opener of ReplBridge.pluginsLatch and never fires there, hanging every eval rather than degrading one. Heuristic and best-effort, sound only while plugin.yml says load: STARTUP — that is what puts onEnable ahead of world loading. Wrong low is the old behavior; wrong high costs a script importing a plugin that attached its urls after this.
