1. GET  /quote              → Best route across 25+ DEXes
2. POST /swap               → Unsigned versioned transaction
3. Sign locally              → Your private key never leaves your machine
4. POST /send-transaction   → Submit via Yellowstone Jet TPU
5. GET  /transaction/{sig}  → Confirm status (pending/confirmed/failed/expired)
