-### Rebuild Database
-
-Rebuild the database by deleting all chunks & embeddings and re-indexing all documents:
-
-```bash
-haiku-rag rebuild

 Use this when you want to change things like the embedding model or chunk size for example.

-### Migrate from SQLite to LanceDB
-
-Migrate an existing SQLite database to LanceDB:
-
-```bash
-haiku-rag migrate /path/to/old_database.sqlite

-This will:
-- Read all documents, chunks, embeddings, and settings from the SQLite database
-- Create a new LanceDB database with the same data in the same directory
-- Optimize the new database for best performance

-The original SQLite database remains unchanged, so you can safely migrate without risk of data loss.
