Fixes #5468
EngineRequestdeclared_queryas required, but the property is set lazily byprepare()and doesn't exist on a rawIncomingMessage. This caused a TypeScript error when passing a plainIncomingMessagewhere anEngineRequestis expected; for example, in Nuxt integrations following the official guide.Before: Any code that worked with
EngineRequestdirectly would get a TypeScript mismatch error because_querywas required but not present on the underlyingIncomingMessage.After:
_queryis typed as optional inEngineRequestand in theTransportconstructor, which correctly reflects the lifecycle of the property: it may not be set at construction time, but is always guaranteed to be present by the time any transport logic runs.transports/index.tsis also updated for consistency.No tests added - this is a TypeScript-only change with no runtime behavior difference.
