Bridge architecture

Mint/burn flow follows the same pattern as wSMT (PR #516):

• User deposits RATR to custodian address on Ratatoskr chain
• Relayer detects deposit, calls bridge.mint() on Alephium → wRATR sent to user
• User burns wRATR on Alephium → relayer detects, sends RATR back to user's address

Bridge contracts owned by a Ledger Group 0 address.

Reference

Follows the same pattern as wSMT (PR #516, merged 2026-04-17).
