"""Domain services - interfaces for infrastructure operations.

The concrete launchers are NOT re-exported here. They were, via a deprecated
shim that warned from v1.0.2 onward and survived the 2.0 major; import them
from ``mcp_hangar.infrastructure.launchers``, which is where they live. What
this package offers for launching is the port, ``IMcpServerLauncher``.
