After the inner store accepts an event (insert succeeds), register
the caller's instance with the interner so subsequent reads of the
same id return the same `===` reference. This means an event that
was just inserted and is then queried back resolves to the original
in-memory object, not a freshly-deserialized clone.
Same in transaction { }: every accepted event is interned after the
inner transaction commits. If the body throws or inner rolls back,
nothing is interned (accepted list is discarded).
The decorator still does not *substitute* the caller's event with a
previously-cached one — same-id-different-sig collisions resolve
the new event into the cache without overwriting (intern() is
first-seen-wins). The caller keeps the instance they passed in.
All cache + store + projection tests pass.
