refactor(storage): drop StorageBundle + legacy EventStore, add HttpEventStore

- Remove legacy pw.binom.agentik.messageStore.events.EventStore (EventRecord,
  EventType) and all three impls (in-memory, sqlite, ksqlite) + tests + .sq
- Drop :storage-bundle module entirely; ChatAgent / ChatConversation /
  ConversationLoop / DebugRoutes now take stores individually
  (conversationStore, messageStore, workingMemoryStore, reflectionStore,
  eventStore) instead of StorageBundle
- Delete server endpoints /events/replay and /conversations/{id}/events/replay;
  Route.agentikAgent no longer takes eventStore param
- Add :client/HttpEventStore implementing :event-store/EventStore over HTTP:
  events() -> GET /events/all, agentEvents() -> GET /events,
  conversationEvents(convId) -> GET /conversations/{id}/events;
  exposed via AgentClient.eventStore
- :event-store: add macosX64/macosArm64/linuxArm64 targets to match :client KMP
- :working-memory-api: drop api dep on :message-store-api (no longer needed)
- :storage-{inmemory,sqlite,ksqlite}: drop deps on :storage-bundle
