Registry mapping Phase 3 event atoms to their canonical schema modules (D3-66, D3-68).
The registry covers all 24 Phase 3 event types. Seven events have
fully-typed schema modules (created, updated, canceled,
plan_swapped, invoice.paid, refund.created, card.expiring_soon);
the remaining 17 are minimal stubs that establish the
Accrue.Events.Upcaster contract at schema_version: 1 but do not
yet enumerate every typed field. Future revisions can expand any
stub into a typed struct without touching the registry shape.
Usage
iex> Accrue.Events.Schemas.for(:"subscription.created")
Accrue.Events.Schemas.SubscriptionCreated
iex> Accrue.Events.Schemas.for(:"unknown.event")
nil
iex> Accrue.Events.Schemas.count()
24
