jif c4f2746c43 Keep MCP tool calls bound to their thread (#36355)
## Why

Threads can configure the same MCP server name with different runtimes. Tool calls
must use the runtime associated with the thread that issued the call.

## What changed

- Route MCP readiness checks and call preparation through the invoking session.
- Add regression coverage that alternates calls between two threads and verifies
  that each thread continues using its own MCP server process and configuration.
