Crate narwhal_commands 

Stateless command and helper modules for narwhal.

Each module here is a self-contained piece of the host application that does not own runtime state: completion engine, export pipeline, connection wizard, snippet store, DDL/EXPLAIN helpers, inline cell editing, statement extraction and the :-prompt command dispatch.

Hosts (narwhal-app, the headless CLI, the MCP server) call into these modules with the data they own; nothing here reaches back into the host.
