Pre-merge author checklist

I've followed MetaMask Contributor Docs and MetaMask Extension Coding Standards.
I've completed the PR template to the best of my ability
I’ve included tests if applicable
I’ve documented my code using JSDoc format if applicable
I’ve applied the right labels on the PR (see labeling guidelines). Not required for external contributors.

Pre-merge reviewer checklist

I've manually tested the PR (e.g. pull and build branch, run the app, test code being changed).
I confirm that this PR addresses all acceptance criteria described in the ticket it closes and includes the necessary testing evidence such as recordings and or screenshots.

Note

Medium Risk
Adds a new persisted-state migration and changes where snap sourceCode is stored/retrieved, which can impact snap execution/installation and upgrade paths if the migration or storage adapter misbehaves.

Overview
Snap storage is moved toward StorageService. SnapController’s restricted messenger now allows StorageService actions (setItem/getItem/removeItem/clear) and subscribes to SnapsRegistry:stateChange.

Persisted snap sourceCode is migrated out of controller state. New migration 193 copies each snap’s sourceCode from SnapController.snaps into browser storage via BrowserStorageAdapter and deletes it from state, with defensive error reporting and updated migration/version fixtures.

Telemetry/UI sanitization is updated accordingly. State sanitization and tests stop treating snap sourceCode as a “large” field to strip, and unit test setup globally mocks BrowserStorageAdapter with an in-memory adapter (with browser-storage-adapter tests opting into the real implementation).
