* This file resolves trilium data path in this order of priority:
* - if TRILIUM_DATA_DIR environment variable exists, then its value is used as the path
* - if "trilium-data" dir exists directly in the home dir, then it is used
* - based on OS convention, if the "app data directory" exists, we'll use or create "trilium-data" directory there
* - as a fallback if previous step fails, we'll use home dir
