Module import 

Import functionality for the task-graph database.

Provides methods to import data from a JSON snapshot into the database. Supports multiple import modes:

• Fresh: Import into an empty database (fails if data exists)
• Replace: Clear existing project data and import (default with –force)
• Merge: Add missing items, skip or overwrite existing (future)

Handles foreign key constraints by:

• Deleting tables in reverse order (children first) when clearing
• Inserting tables in forward order (parents first) when importing

Rebuilds FTS indexes after import.
