Cymule Timer Activation

cymule-activation-timer is a durable logical timer source backed by SQLite. Schedules retain a stable activation ID, timer ID, due observation and typed value. A timer is acknowledged only after Cymule commits its activation CAS; lost acknowledgement redelivers the same delivery.

The default SystemClock observes Unix milliseconds. Tests and simulations can inject a deterministic Clock. Clock values are substrate observations, not canonical framework time.
