Transaction Lifecycle

Transactions progress through these stages:

pending → simulating → policy_eval → approval_gate → signing → submitting → confirmed
                                  ↓                                       ↓
                                  └──────────────→ failed ←──────────────┘

Poll the transaction status until it reaches confirmed or failed.
