Minor Changes

• 9e54de3: Add consumer-facing state and startup-input extractors. Machine.Snapshot, Machine.Value, and Machine.SnapshotAt accept either the object returned by Machine.states or a machine definition, while preserving exact path validation and excluding control-only paths from Value.

  Machine.Machine.Input<M> now extracts the decoded startup value and is never when the machine uses Schema.Void. Code that needs the startup schema should migrate from Machine.Machine.Input<M> to Machine.Machine.InputSchema<M>; code that previously used Machine.Machine.Input<M>["Type"] can use Machine.Machine.Input<M> directly.

• d6d19c1: Replace Machine.invoke and its object-configuration helper types with state-local fluent invocation chains. Select an Effect, Stream, timer, process logic, or child from the handler's from parameter, then handle every reachable lifecycle channel before returning the chain:

  machine.handle({
    Loading: {
      invoke: (from) =>
        from
          .effect("load", () => loadUser())
          .onDone((to) => to.full.Ready())
          .onFailure((to) => to.full.Failed())
    }
  })

  Return an array of completed chains for multiple activities. Sources and child descriptors remain reusable, while keeping the invocation declaration local preserves exact owner-state, event, parent, output, failure, element, snapshot, and service inference.
