• I've updated the test suite for new or updated code as appropriate
• I've updated documentation (JSDoc, Markdown, etc.) for new or updated code as appropriate
• I've communicated my changes to consumers by updating changelogs for packages I've changed
• I've introduced breaking changes in this PR and have prepared draft pull requests for clients and consumer packages to resolve them

Note

Medium Risk
Expands each controller’s public messenger surface area and changes how actions are registered/called, which could affect downstream consumers relying on previous action typings/exports, though core logic is largely unchanged.

Overview
Standardizes messenger exposure for DelegationController and GatorPermissionsController by registering all public methods via messenger.registerMethodActionHandlers and adding generated *-method-action-types.ts unions for the corresponding action types.

Updates exports/types so DelegationControllerGetStateAction and the new method-action types are publicly available, and refactors tests to invoke controller behavior through rootMessenger.call(...) rather than direct method calls. Adds tsx plus a generate-method-action-types script to both packages and records the API exposure in changelogs.

A couple of things, but otherwise looks good.
