The registration surface whose return types carry the widening.
Every method returns the **same runtime object**, re-typed. Subscriptions, effects,
middleware, the dedup cache, both buses and any in-flight call() are untouched; the only
runtime effect is the registration itself.
Note there is no explicit type parameter for the added event map anywhere. It is inferred
from a single value position, so the partial-inference problem never arises and no call
site needs a type argument or a cast.
Mounts a slice and hands back both the widened store and a disposer.
The disposer is **library-private**: after it runs, the widened type still promises a
slice that is gone. Application code should take StoreDecoration.withSlice
instead, which returns no disposer at all.

Registers middleware and returns the store widened by whatever event map it declares.
Only the **spec form** can widen: MiddlewareFunction's event parameter is
EventUnion<EM>, a mapped type TypeScript cannot infer EM back out of. A bare function
therefore contributes {}.
