This change reorganizes the `tx/transactors` directory for consistency and discoverability. There are no behavioral changes, this is a pure refactor. Underscores were chosen as the way to separate multi-words as this is the more popular option in C++ projects. Specific changes: - Rename all subdirectories to lowercase/snake_case (`AMM` → `amm`, `Check` → `check`, `NFT` → `nft`, `PermissionedDomain` → `permissioned_domain`, etc.) - Merge `AMM/` and `Offer/` into `dex/`, including `PermissionedDEXHelpers` - Rename `MPT/` → `token/`, absorbing `SetTrust` and `Clawback` - Move top-level transactors into named groups: `account/`, `bridge/`, `credentials/`, `did/`, `escrow/`, `oracle/`, `payment/`, `payment_channel/`, `system/` - Update all include paths across the codebase and `transactions.macro`
