"""The Claude management surface: /claude API CRUD + admin gating, the generation that
applies it (settings permissions/plugins, the --mcp-config file, user-level skills), and
the spawn integration that ties them together.

Spawns go through the ``fake_launch`` seam; the conftest ``env`` fixture points $HOME at
the per-test tmp dir, so skill syncs never touch a real ``~/.claude``.
