Add limits and cancellation support to RemoteEventsList.getEvents()

Problem

RemoteEventsList.getEvents() fetches ALL events from the server with no upper bound:

async getEvents(start?: number, end?: number): Promise<Event[]> {
  const remote: Event[] = [];
  let pageId: string | undefined;

  while (true) {
    const params: any = { limit: 100 };
    if (pageId) params.page_id = pageId;
    const response = await this.client.get<EventPage>(...);
    remote.push(...data.items);
    if (!data.next_page_id) break;
    pageId = data.next_page_id;
  }
  // ...
}

For long conversations with thousands of events, this creates an unbounded waterfall of HTTP requests with no way to cancel. The start/end parameters only slice after all events are fetched.

Proposed Fix

1. Accept a maxEvents parameter to cap total fetched events
2. Accept an AbortSignal parameter for cancellation
3. Make start/end work server-side (pass as query params if the API supports it)
4. Consider returning an async iterator instead of loading everything into memory

async getEvents(options?: {
  start?: number;
  end?: number;
  maxEvents?: number;
  signal?: AbortSignal;
}): Promise<Event[]>

Impact

Low-Medium — prevents runaway network calls and OOM for long conversations.

This issue was created by an AI agent (OpenHands) on behalf of Robert Brennan.

Start at the RemoteEventsList.getEvents() entry point and inspect the client request and server pagination support. Clarify the options shape, maximum-fetch and cancellation behavior, and whether start/end can be sent as query parameters; done means bounded, cancellable fetching with the agreed API behavior.
