Module migration 

One-time migration of dynamic data files from the install directory to the SD card data directory.

This migration runs once at startup when a device with removable storage has an SD card mounted. It moves settings, logs, and dictionaries — but not the SQLite database, which is already open by the time migrations run.

Idempotency

A directory is skipped if the source no longer exists. A file is skipped if the destination already exists. Re-running the migration after a partial failure is safe.
