v3.0.0

3.0.0 (2026-07-25)

⚠ BREAKING CHANGES

• outbox: IOutboxRepository.MarkFailed takes maxAttempts and
  backoff; IOutbox.Enqueue takes an optional context ahead of the
  cancellation token; IOutboxMessage gains NextAttemptAt and Context.
  Custom implementations of either interface must be updated. Existing data
  survives: the PostgreSQL table picks up its two columns through ADD COLUMN IF NOT EXISTS, while EF Core deployments need a migration for the new
  NextAttemptAt/Context properties and the widened outbox index.

Features

• outbox: carry context, retry with backoff and claim under lock (319abb9)
