```ruby
http_transport.session_id # => "abc123..."
http_transport.protocol_version # => "2025-11-25"
http_transport.protocol_version # => "2026-07-28"
```
If the server terminates the session, subsequent requests return HTTP 404 and the transport raises `MCP::Client::SessionExpiredError` (a subclass of `RequestHandlerError`). Session state is cleared automatically; callers should start a new session by calling `connect` again.
