Koichi ITO 88d9bed69d Reject POST requests without session ID in stateful mode 
Per the MCP specification (Streamable HTTP > Session Management):

> Servers that require a session ID SHOULD respond to requests without an `Mcp-Session-Id` header
> (other than initialization) with HTTP 400 Bad Request.

https://modelcontextprotocol.io/specification/2025-11-25/basic/transports#session-management

Previously, non-initialize POST requests without `Mcp-Session-Id` in stateful mode were processed
with HTTP 200 (for regular requests) or HTTP 202 (for notifications/responses).

This change adds an explicit check in `handle_post` to return HTTP 400 Bad Request when the session
ID is missing in stateful mode for all non-initialize requests, aligning with the specification.
