"""Test setup for framework tests.

Two responsibilities:

1. **MCP submodule bindings** -- ensures ``framework.loader`` submodules
   are attached to the parent package so monkeypatch's dotted-string API
   (``monkeypatch.setattr("framework.loader.foo.Y", ...)``) resolves even
   when no test has imported the submodule yet.

2. **Global hive-home isolation** -- redirects ``~/.hive`` to a per-test
   tmp directory for every test in the suite. Without this, any test
   that instantiates a real ``SessionManager`` or calls ``_start_queen``
   leaks real session directories into the developer's actual
   ``~/.hive/agents/queens/`` tree, polluting the queen DM history and
   occasionally hijacking the live server's navigation.
