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).
