- **added** — Add `createSystem({ registry })` for declaring typed actor registry keys and creating actors in that system, with registry keys assigned via `registryKey` on invokes, spawned actors, and root actors
- **added** — Static transition config objects may now include a shallow `context` patch that is shallow-merged with the current context

###### Major Changes

-   89895f9: Add `createSystem({ registry })` for declaring typed actor registry keys and creating actors in that system.

    Registry keys are assigned with `registryKey` on invokes, spawned actors, and root actors created from the system. Registry keys are checked against the declared registry when using `createSystem`.

    ```ts
    const system = createSystem({
      registry: {
        receiver: receiverLogic
      }
    });

    const machine = system.setup().createMachine({
      invoke: {
        src: receiverLogic,
        registryKey: 'receiver'
      }
    });

    const actor = system.createActor(machine).start();

    system.get('receiver')?.send({ type: 'HELLO' });
    ```

###### Patch Changes

-   89895f9: Static transition config objects may now include a shallow `context` patch.

    ```ts
    createMachine({
      context: { draftAnyway: false, count: 0 },
      initial: 'idle',
      states: {
        idle: {
          on: {
            DRAFT_ANYWAY: {
              target: 'drafting',
              context: { draftAnyway: true }
            }
          }
        },
        drafting: {}
      }
    });
    ```

    The patch is shallow-merged with the current context, just like `context` returned from a transition function. Setup-typed machines still require any keys needed by the target state's narrowed context.
