status: done_current_scope task: 建立 IndexedDB schema 和 migration
web/app/src/storage/migrations.ts upgrades blender-web-metadata to schema
version 4 while preserving the existing smoke store. It creates project,
asset, snapshot, operation_log, setting and migration stores and
records each schema migration. Schema 4 adds content-addressed asset metadata;
StorageWorker info, project layout and Worker-restart discovery are covered by Playwright.
Downgrade/rollback across older deployed browser builds remains outside the current scope.
