…PluginError hierarchy - New models.py: PluginState (StrEnum) with LOADED/STARTED/STOPPED/FAILED; PluginDescriptor mutable dataclass tracking per-plugin runtime state - decorators.py: Plugin dataclass gains optional name/author fields; @plugin decorator gains matching kw-args; name defaults to id - exceptions.py + kernel/__init__: PluginException base + PluginLoadError, PluginStartError, PluginStopError, PluginStateError subclasses - resolver.py: PluginResolutionError now extends PluginException
…/get_plugin with cascade - registry.py: get_extension() returns single highest-priority extension; raises ValueError if point not registered or has no extensions - manager.py: track _descriptors dict[str, PluginDescriptor]; _transition() helper for state changes; start_plugin() cascades transitive deps in topo order, skips STARTED; stop_plugin() cascades transitive dependents in reverse order, skips STOPPED/LOADED; get_plugin() returns descriptor or None; start_all/stop_all wire state transitions; remove() drops descriptor - plugins/__init__.py: re-export PluginDescriptor, PluginState
- test_plugin_lifecycle.py: 14 tests covering start_plugin cascade (A←B←C), skip-already-started, stop_plugin reverse cascade, get_extension happy/error paths, FAILED state on hook error, get_plugin none/descriptor, name/author in descriptor, start_all/stop_all state marking - test_plugins_auto_configuration.py: 7 tests verifying PluginsAutoConfiguration markers, on_property condition key, bean factory types and registry identity
