 /**
  * Proto3 `oneof` JSON mapping — the payload variant's field name appears as a *sibling* of the
  * message's other fields (no wrapper key, no discriminator value), e.g. `{"id":"e1","text":"hi"}`
  * or `{"id":"e1","code":5}`. Achieved by composing two existing features rather than needing
  * dedicated oneof codegen:
  *   - `@GhostSerialization(inferred = true)` on the sealed hierarchy: picks the subclass whose
  *     required property set matches whichever wire keys are present (no discriminator field).
  *   - `@GhostWrappedKeys` on the property: collapses those sibling wire keys into one property,
  *     assembling a synthetic wrapper object only from the keys actually present on the wire —
  *     which is exactly what the `inferred` dispatch above needs to pick the right subclass.
