Update structure.md to reflect all tool annotations and new tools

- Update get-annotated-message description: all tools now have
  tool-level annotations, not just this one
- Add missing tool entries: simulate-research-query,
  trigger-elicitation-request-async, trigger-sampling-request-async
- Add these tools to the file tree listing

Emits a primary `text` message with content `annotations` (`priority`, `audience`) that vary by `messageType` (`"error" | "success" | "debug"`), and optionally includes an annotated `image` (tiny PNG) when `includeImage` is true.

+- `simulate-research-query.ts`
+  - Registers a `simulate-research-query` task-based tool that demonstrates the MCP Tasks feature (SEP-1686). Simulates a multi-stage research operation with progress updates. If the query is marked as ambiguous and the client supports elicitation, it pauses mid-execution to request clarification via `elicitation/create`. Uses `server.experimental.tasks.registerToolTask()` with `execution: { taskSupport: "required" }`.
 - `trigger-elicitation-request.ts`
   - Registers a `trigger-elicitation-request` tool that sends an `elicitation/create` request to the client/LLM and returns the elicitation result.
+- `trigger-elicitation-request-async.ts`
+  - Registers a `trigger-elicitation-request-async` tool that demonstrates bidirectional MCP tasks for elicitation. Sends an elicitation request with task metadata, then polls the client's `tasks/get` endpoint for completion status before fetching the final result.
 - `trigger-sampling-request.ts`
   - Registers a `trigger-sampling-request` tool that sends a `sampling/createMessage` request to the client/LLM and returns the sampling result.

   - Registers a `get-tiny-image` tool, which returns a tiny PNG MCP logo as an `image` content item, along with surrounding descriptive `text` items.
 - `trigger-long-running-operation.ts`
-  - Registers a `long-running-operation` tool that simulates a long-running task over a specified `duration` (seconds) and number of `steps`; emits `notifications/progress` updates when the client supplies a `progressToken`.
