Add tests and implement timeline ingestion options with NATS and Redis subscribers

- Introduced `BinaryReachabilityLifterTests` to validate binary lifting functionality.
- Created `PackRunWorkerOptions` for configuring worker paths and execution persistence.
- Added `TimelineIngestionOptions` for configuring NATS and Redis ingestion transports.
- Implemented `NatsTimelineEventSubscriber` for subscribing to NATS events.
- Developed `RedisTimelineEventSubscriber` for reading from Redis Streams.
- Added `TimelineEnvelopeParser` to normalize incoming event envelopes.
- Created unit tests for `TimelineEnvelopeParser` to ensure correct field mapping.
- Implemented `TimelineAuthorizationAuditSink` for logging authorization outcomes.
