TestingModuleOptions

What a testing module is built from: the classes a test needs, and the app whose global stages apply.

The controllers the module builds, with every class they inject.

Providers for what those classes inject, in any shape @MeoCord({ providers }) takes.

The @MeoCord app class, whose global guards, interceptors and filters run with each handler's own, and whose translator, presenter, message options, theme, cooldown store and policy, and observers the module uses. A CooldownStore in providers takes the store's place. Its controllers, services and providers are not registered: list the ones a test needs, or build the whole app with MeoCordTestingModule.fromApp.

@Observer classes told about each call invoke, dispatch and emit make, after the app's own. The module waits for them before a call resolves, so a test sees what they were told.

How long close() waits, in milliseconds, for the calls under way, the cooldown store's operations and the onShutdown hooks, as shutdownTimeout in meocord.config.ts bounds the bot's shutdown: from 0 to 2147478647, and 10000 unless set. A test whose fake store never answers, or whose onShutdown never settles, sets it short.
