Migration scripts must NEVER import or reference:
any for migration input/output)createXxx()Why: The codebase evolves. A migration written today references code that may change tomorrow. When that constant changes, the migration silently breaks — it now migrates to the new shape, not the shape that existed when the migration was written.
In this repo, config migration registries should auto-discover migration files from src/utils/config/migration-scripts/v*-to-v*.ts (for example via import.meta.glob), and the registry must:
fromVersion and toVersion from the filenamev001-to-v003Do not silently map only the target version and assume filenames are correct.
Do not let generic config read helpers or content-script paths import migration registries unless they really perform migration.
Prefer to isolate migration-aware reads/writes into dedicated modules for import/sync/restore flows, so normal runtime paths do not bundle all migration scripts unnecessarily.
