Pranit 80b2bbecfb Explain oversized MCP replies and stop fetching them again ...

- When a stdio MCP server replies with more than 16 MiB, the model is told the reply was too large and fx restarted the server, instead of "the server went away".
- When an HTTP MCP server replies with more than 16 MiB, fx ends the call at once and tells the model the reply was too large, instead of "the server went away".
- fx no longer resumes an HTTP stream (2025 protocol) to fetch an oversized reply again. Before, it downloaded the same reply up to two more times.
- fx no longer requests an oversized tool list again from an HTTP server on the 2026 protocol.
- The debug trace logs each dropped reply with the server, transport, and reason.
