Subject: [PATCH] fix: ensure data directory exists before SQLite engine init

On fresh installs the data/ dir may not exist, causing SQLite to create a
stub file without write permissions. mkdir(parents=True, exist_ok=True) runs
at import time before any DB operation.

Also add data/.gitignore to prevent homelab.db from ever being committed.
