- Created src/application_context.py as DI container with TYPE_CHECKING imports
- server.py now instantiates all services in dependency order via ApplicationContext
- Fixed infinite recursion bug: 48 instance methods renamed with underscore prefix
to avoid shadowing by same-named @classmethod forwarders
- ZeroconfServer: instantiate Zeroconf() in __init__, add _sync_class() to
configure forwarder, direct _configure/_start calls during wiring
- Config, EngineManager, PreviewManager: all forwarders and _sync_class() intact
- RenderQueue: load_state and subscribe moved to __init__, threading.Lock retained
- DistributedJobManager: subscribe_to_listener moved to __init__
