/**
 * task-6-rereview2.md I-A: `PluginRuntimeService.onApplicationBootstrap`'s
 * absent-ORM branch (`plugin-runtime.service.ts:~296-300`) was dead
 * suite-wide — every existing construction of the service that reaches
 * `onApplicationBootstrap` (boot-registry-order.test.ts, plugin-host.ts) hands
 * it a real MikroORM. That branch is the half of the boot RULING
 * (task-6-rereview.md §2) that makes "skip loudly, never abort app.init()"
 * defensible: dropping the `logError` call, or falling through to `activate`
 * anyway, would ship green with no test failing. This file pins it directly.
