Note

Medium Risk
Changes messenger action registration and exported action type surface for multiple controllers; consumers relying on old action types or unexposed actions may see TypeScript/API breakage despite deprecations.

Overview
Standardizes how PermissionController, SubjectMetadataController, PermissionLogController, and SelectedNetworkController expose public methods via the messenger by switching to registerMethodActionHandlers with explicit MESSENGER_EXPOSED_METHODS lists.

Adds auto-generated *-method-action-types.ts files and re-exports their strongly named ...Action types from package index.ts, while deprecating older action type aliases (e.g., GetPermissionControllerState, SelectedNetworkControllerGetSelectedNetworkStateAction).

Updates tests to invoke controllers through messenger calls (and adds minimal mocking for ApprovalController:addRequest), and adds a generate-method-action-types script plus tsx devDependency in affected packages.

Just a few comments, but otherwise looks good to me.

LGTM! (well, aside from the conflicts)

[mcmire]

This type should really be called SelectedNetworkControllerGetStateAction :( Oh well. Maybe we can fix this in another PR.

[Mrtenz]

Agreed. Had to fix conflicts anyway, so I fixed this type too.
