Note

High Risk
Major @metamask/account-tree-controller propagates through many core packages; clients must adopt new messenger actions and handle breaking account-tree APIs even though this PR only versions artifacts.

Overview
Monorepo release 1194.0.0 cuts new package versions and refreshes changelogs, package.json dependency ranges, and yarn.lock. There is no application source change in the diff—only release metadata.

The headline bump is @metamask/account-tree-controller 8.0.0 (from 7.6.1), documenting the already-shipped breaking AccountTreeController:importState / exportState APIs (extra messenger registrations for multichain account creation and keyring access, password when exporting secrets). Downstream packages (assets-controller, assets-controllers, core-backend, earn-controller, bridge/transaction-pay, etc.) are republished with ^8.0.0 on account-tree and aligned bumps on @metamask/multichain-account-service ^13.0.2 and @metamask/core-backend ^8.1.2.
