Note

Medium Risk
Adds new state-mutating behavior driven by TransactionController events; incorrect status/type handling or unsubscribe logic could cause missed deletions or lingering subscriptions, though coverage is included via new unit tests.

Overview
Adds a new DelegationController:awaitDeleteDelegationEntry method/action that subscribes to TransactionController:transactionStatusUpdated and, based on transaction type/status (including replacement via replacedById), deletes a delegation entry and optionally stores a provided replacement entry.

Updates the controller’s messenger types and build refs to allow TransactionController events, adds @metamask/transaction-controller as a dependency, exports the new action type, and adds a focused test suite covering confirmation, drop/fail/reject/cancel, replacement chaining, and unsupported types.
