Ates Goral 07226b7cf1 Track Mcp-Session-Id and protocol version in HTTP client
Per the Streamable HTTP spec, if the server returns an Mcp-Session-Id
header during `initialize`, the client MUST include it on subsequent
requests. Capture the session ID and protocol version from the
`initialize` response and attach them automatically on subsequent
POSTs.

Per the Protocol Version Header section of the spec, the client MUST
also include `MCP-Protocol-Version` on all subsequent requests so the
server can respond based on the negotiated protocol version.

Map 404 responses to a new `SessionExpiredError` (a subclass of
`RequestHandlerError` for backward compatibility) and clear local
session state so callers can start a fresh session with a new
`initialize` request, as required by the spec.
