feat: bridges, PMM, flash workflow, token-aggregation, and deployment docs
- CCIP/trustless bridge contracts, GRU tokens, DEX/PMM tests, reserve vault. - Token-aggregation service routes, planner, chain config, relay env templates. - Config snapshots and multi-chain deployment markdown updates. - gitignore services/btc-intake/dist/ (tsc output); do not track dist. Run forge build && forge test before deploy (large solc graph). Made-with: Cursor
