 - The repo now also includes a built-in HydrusNetwork provider in [plugins/hydrusnetwork/__init__.py](plugins/hydrusnetwork/__init__.py). Its Hydrus client API now lives in the plugin-owned package [plugins/hydrusnetwork/api/__init__.py](plugins/hydrusnetwork/api/__init__.py), its registry-facing store adapter lives in [plugins/hydrusnetwork/store_proxy.py](plugins/hydrusnetwork/store_proxy.py), and its heavy internal operations live in [plugins/hydrusnetwork/store_backend.py](plugins/hydrusnetwork/store_backend.py). This `plugins/<name>/api/` package shape is the intended pattern for plugin-owned API helpers going forward. The provider now resolves configured Hydrus instances directly from plugin config instead of routing back through `Store.registry`; the proxy exists only so generic store callers can still target configured Hydrus stores. [API/HydrusNetwork.py](API/HydrusNetwork.py) and [Store/HydrusNetwork.py](Store/HydrusNetwork.py) are legacy compatibility shims only, and store discovery prefers the plugin-owned Hydrus hook over those shims.
