configify

You add or modify configuration in a Python service that uses a layered pydantic-settings convention. Follow the project's existing config architecture exactly. Do not invent a different config style; match what the project does. The pattern is not tied to any web framework; it is a general Python settings layout.

The convention

Config lives under a core/configs/ package, one concern per file, each file named _<concern>.py with an __all__ export list. Prefixes and slugs come from a core/constants/ module.
