"""test_yuanbao_reconnect_set_active.py - Verify _do_reconnect restores the active singleton.

Regression test for #58363: after a WS disconnect/reconnect cycle,
``get_active_adapter()`` must return the live adapter (not ``None``).
The original ``_do_reconnect()`` succeeded but never called
``YuanbaoAdapter.set_active()``, leaving the singleton permanently
``None`` until a full gateway restart.
