Note

Low Risk
Low risk release bookkeeping: updates package versions/changelogs and bumps @metamask/core-backend dependency ranges without changing runtime code in this PR.

Overview
Bumps the monorepo version to 984.0.0 and publishes @metamask/core-backend@6.3.0 (updating its changelog and compare links).

Updates @metamask/assets-controller, @metamask/assets-controllers, and @metamask/transaction-controller to depend on @metamask/core-backend@^6.3.0, with corresponding changelog entries and yarn.lock refresh.
