Provides a reusable builder that packages the event-log-in → derived-state-out pattern for deterministic tests. Implements fixed clock and deterministic event ID generation to ensure byte-identical event JSON across test runs with same payloads. Acceptance criteria met: - Two harnesses fed same payloads yield byte-identical stored event JSON - Fixed clock ensures timestamp determinism (2026-01-01T00:00:00Z) - Event IDs are deterministically generated (event-0, event-1, etc.) - Supports both givenEvents (append) and rebuild (replay via projection)
