"""Verify src.tool_utils has no project imports beyond src.constants.

If someone adds an import from src.settings, src.database, or any other
|
|
project module inside tool_utils.py, the circular import that this module
|
|
exists to break will silently return a partially-initialized module.
|
|
This test catches that statically.
