/**
* RED scaffold — pushDispatcher (Plan 05-02 turns this GREEN).
*
* Asserts that dispatchPush:
* - Deletes the push_subscriptions row when the push service returns 410 (Gone)
* - Deletes the push_subscriptions row when the push service returns 404 (Not Found)
* - Does NOT delete the row on 201 (success)
* - Does NOT delete the row on transient 5xx errors
*
* These tests fail now because pushDispatcher.ts does not yet exist.
* Run: pnpm --filter @familysync/api exec vitest run tests/lib/pushDispatcher.test.ts
