/**
 * Mocha root hook plugin (see `.mocharc.json`'s `require`) — runs once
 * before every test file's own suites, regardless of load order.
 *
 * Warms up `techStepClassifier` here, with its own generous timeout,
 * instead of leaving it to happen lazily on whichever test file Mocha
 * happens to load first. In production this one-time cost (a `POST
 * /v1/train` round-trip per locale to `services/tech-step-intent-service`,
 * training a real `textcat` on the full `TECH_STEP_TRAINING_DATA` corpus)
 * is paid by `server.ts`'s own `techStepClassifier.warmUp()` before the
 * server ever accepts traffic — but this test suite builds its `app`
 * directly via `createApp()` (see e.g. `tech-step-worker.routes.test.ts`),
 * never running `server.ts` at all. Without this hook, that cost instead
 * landed inside whichever test's own call happened to trigger
 * `_ensureTrained()` first — found the hard way in CI, where training the
 * full corpus took longer than a single test's default 10s timeout
 * (`.mocharc.json`) and failed an otherwise-unrelated test purely because
 * Mocha loaded its file first alphabetically.
 *
 * `resetDatabase()` runs first, deliberately: `_train()`
 * (`tech-step-matcher.ts`) resolves `TechStep.key -> id` from the database
 * alongside training, and a freshly-migrated (never-seeded) test database
 * has no `TechStep` rows yet — every per-test `beforeEach` in this suite
 * already calls `resetDatabase()` again before its own test, which is a
 * no-op duplication of effort but not a correctness problem: `TRUNCATE ...
 * RESTART IDENTITY` plus deterministic re-seeding (`seedReferenceData`)
 * assigns the exact same ids every time, so the `uid -> id` map memoized
 * here from this first reset stays valid for every reset after it.
