🧩 Context

Jetstreamer is a high-throughput toolkit for streaming historical Solana ledger data from the Old Faithful archive. It can replay transactions and blocks from any epoch or slot range at >2.7M TPS and supports multi-threaded, network-based backfill.

While Jetstreamer does not currently include account updates or transaction logs, it is ideal for streaming blocks, transactions, rewards, and epochs into analytics or processing pipelines.

🎯 Objective

Integrate Jetstreamer as a new JetstreamSource for Vixen, allowing slot-range or epoch-based historical replay into the Vixen pipeline.

✅ Acceptance Criteria

• New Jetstream source module integrated with Vixen.
• Supports slot range or epoch input for backfill.
• Emits transactions, blocks, rewards, and epochs into the Vixen pipeline.
• Handles multithreaded replay and out-of-order slot delivery.
• Includes an example or test for replaying a known epoch (e.g., epoch 800).
