docs(everything): update features.md for direct elicitation flow

Update documentation to reflect that simulate-research-query now sends
elicitation requests directly from the background task instead of using
the tasks/result side-channel approach.

 - `toggle-simulated-logging` (tools/toggle-simulated-logging.ts): Starts or stops simulated, random‑leveled logging for the invoking session. Respects the client’s selected minimum logging level.
 - `toggle-subscriber-updates` (tools/toggle-subscriber-updates.ts): Starts or stops simulated resource update notifications for URIs the invoking session has subscribed to.
 - `trigger-sampling-request` (tools/trigger-sampling-request.ts): Issues a `sampling/createMessage` request to the client/LLM using provided `prompt` and optional generation controls; returns the LLM's response payload.
-- `simulate-research-query` (tools/simulate-research-query.ts): Demonstrates MCP Tasks (SEP-1686) with a simulated multi-stage research operation. Accepts `topic` and `ambiguous` parameters. Returns a task that progresses through stages with status updates. If `ambiguous` is true and client supports elicitation, pauses with `input_required` status to gather clarification.

+Use the `simulate-research-query` tool to exercise the full task lifecycle. Set `ambiguous: true` to trigger elicitation - the server will send an `elicitation/create` request directly and await the response before completing.
 
 **Client-side tasks (server calls client):**
 Use `trigger-sampling-request-async` or `trigger-elicitation-request-async` to demonstrate bidirectional tasks where the server sends requests that the client executes as background tasks. These require the client to advertise `tasks.requests.sampling.createMessage` or `tasks.requests.elicitation.create` capabilities respectively.
