Implements StatsDB class with upsert, batch upsert, get_by_hashes, get_all, count, and close methods backed by a WAL-mode SQLite database. Also guards __init__.py relative imports behind __package__ check so pytest can run without ComfyUI context, and removes empty tests/__init__.py to prevent pytest Package collector from traversing into the plugin root.
