beforeEach called ensureStarted(), so every FlashTest field in a class booted
for every test whether or not that test touched it — a class holding four
servers paid for four boots per test. Booting is already lazy on first access,
so the hook was only ever forcing work forward.
Neither hook starts anything now. beforeAll still records that a static field
owns the class-scoped lifecycle, which is what keeps afterEach from tearing a
class-scoped server down after the first test.
This also lets an application read @TempDir inside configure(): JUnit populates
those during instance post-processing, before the first test body but after
extension beforeEach callbacks would have fired.
