Note

Low Risk
Low risk: changes are limited to new TypeScript action type exports, a build-time generation script dependency, and test refactoring; no bridge runtime logic is modified.

Overview
Adds an auto-generated bridge-controller-method-action-types.ts that defines and exports per-method messenger action types (e.g., BridgeControllerFetchQuotesAction) for all public BridgeController methods, and documents/deprecates the older aggregated action types in the changelog.

Updates package.json to support generating these types via a new generate-method-action-types script (adding tsx), and refactors the BridgeController SSE tests to exercise the controller through a real @metamask/messenger instance (rootMessenger.call(...)) instead of a hand-rolled messenger mock.
