- load_plugin: an on_enable() that raises unregisters the instance, so the
next load retries instead of returning True "already loaded".
- get_plugin_info: guard plugin.get_info(); one plugin raising no longer
breaks /api/v3/plugins/installed.
- plugin_state.json and the operation history are written with
atomic_write_text under their lock.
- plugin_loader: module-level lock serialises pip installs across the
parallel startup loaders.
- store_manager._install_via_download: extract dir cleanup moved to finally.
- Test doubles: draw_image() warns (DeprecationWarning; the real
DisplayManager has none), MockDisplayManager.draw_text accepts the real
signature's optional params, VisualTestDisplayManager logs draw errors at
WARNING.
- Docs/comments: compatibility.py method name, PluginState.LOADED meaning,
brittle schema count, why _report_skip_once uses setdefault.
- Remove unused PluginOperationQueue.get_active_operations().
