Low risk: changes are limited to version/changelog metadata and do not affect runtime behavior.

Overview
Bumps the root package.json version from 842.0.0 to 843.0.0.

Updates @metamask/ramps-controller’s CHANGELOG.md footer links to treat 10.1.0 as the latest release (adjusts the [Unreleased] compare target and adds a [10.1.0] compare link).
