Minor Changes

• b1a1f75: Make Machine.encodeSnapshot return a canonical JSON representation or fail
  with MachineSchemaEncodeError. Encoded state values, completion outputs, and
  history values are now typed as Schema.Json; rich schema values use their
  canonical JSON codecs, while cycles and other non-JSON values fail at the
  machine boundary instead of causing a later serialization crash.
  Declared Schema.Void and Schema.Undefined completion outputs now use their
  canonical null encoding; an omitted output is reserved for final states that
  do not declare an output schema.

  ClusterMachine.make now requires JSON-encoded state, completion-output, and
  public input-event schemas. Keep process-local capabilities in services,
  adapters, or internal events, and give transported values an explicit JSON
  codec. Cluster snapshot encoding failures are reported as
  SnapshotEncodeFailure without advancing the checkpoint.

  MachineTest.observedGraph continues to support process-local state. Its node
  encoded field is now optional: portable snapshots retain their canonical JSON
  form, while non-portable snapshots use local structural identity and omit it.
  Snapshot encoding failures no longer appear in the operation's error channel.
