Charlie Marsh 7d1492ffab Isolate MCP inputs and timeouts for callers sharing a connection (#57196) ...

## Why

Concurrent requests on a shared MCP connection need to route prompts to their own callers and pause only their own timeouts while awaiting input.

## What changed

- Add `call_tool_with_elicitation` and `read_resource_with_elicitation` with per-request callbacks and timeout pause state, requiring MCP protocol `2026-07-28`.
- Share continuation handling between tool calls and resource reads, and assign globally unique input IDs across requests and connections.
- Add `enable_request_cancellation` to extend cancellation on dropped response futures to catalog, resource, and custom requests.

## Testing

Add or extend tests for concurrent form and URL input routing, unique prompt IDs, independent native verification cancellation and timeouts, resource continuations, and remote cancellation when resource or custom request futures are dropped.
