- `messages.py`: Defines base classes for `Message`, `Snapshot`, and `Event`, along with `SnapshotChannel` and `EventChannel` protocols. It also includes concrete message types for state, reset, model, perturbation, pause state, and exit events.
- `endpoints.py`: Provides `ViewerEndpoint` and `SimEndpoint` classes to manage message routing between the simulation and the viewer via the defined channels. A `make_endpoints` function is included to create both endpoints.
