 		Fix stale request context in StatefulProxyClient handlers (#3172) 
* fix: restore request context in StatefulProxyClient handlers

StatefulProxyClient reuses sessions across requests, so its receive-loop
task inherits a stale request_ctx ContextVar from the first request.
Server-initiated messages (elicitation, sampling, etc.) that depend on
related_request_id routing get sent to a closed stream and hang forever.

Closes #3169

* chore: Update SDK documentation

6e22914360 Move relay logic to elicitation.py, fix related-task metadata key 
Moves relay_elicitation() into elicitation.py so it can reuse
handle_task_input() for the Redis push instead of duplicating that logic.
notifications.py just detects the trigger and calls it.

Also fixes the related-task metadata key from modelcontextprotocol.io/ to
io.modelcontextprotocol/ to match the current spec:
https://modelcontextprotocol.io/specification/2025-11-25/basic/utilities/tasks

feat: distributed notification queue + BLPOP elicitation for background tasks
 2026-02-10 15:32:55 -05:00

361eb08f42 Relay task elicitation through standard MCP protocol 
When a background task calls ctx.elicit(), the notification subscriber now
detects the input_required notification and sends a standard elicitation/create
request to the client via session.elicit(). The client's elicitation_handler
fires, and the relay pushes the response to Redis for the blocked worker.

This means clients can respond to background task elicitation using the same
elicitation_handler they'd use for any other elicitation — no need to interact
with Redis or call handle_task_input() directly.
