Explanation

This PR cuts monorepo release 875.0.0 and publishes a new @metamask/ramps-controller version so consumers can pick up ramps work that is already on main but was not included in the previous npm publish train.

Current state

• main includes ramps updates (notably messenger exposure and getOrder wallet/query handling), documented under Unreleased in packages/ramps-controller/CHANGELOG.md.
• Without a release, clients stay on the last published @metamask/ramps-controller and do not get those fixes/features from the registry.

What this change does

• Bumps the monorepo root version to 875.0.0 (release branch convention).
• Releases @metamask/ramps-controller@12.0.1, with changelog entries moved from Unreleased into [12.0.1] per Keep a Changelog.
• Added: public RampsController methods exposed via the messenger (#8221).
• Fixed: getOrder wallet handling so requests and orderStatusChanged payloads stay consistent (#8251).

Note for reviewers

• If this branch also bumps other workspace packages (lockfile / dependents), that is to satisfy release tooling and dependency constraints for anything else selected for 875—not arbitrary scope creep.
