patch

Fix the generated SSE sseRequest helper to reference Schema.ConstraintDecoder instead of the no-longer-exported Schema.Decoder.

For specs with text/event-stream responses the generator emitted a helper typed as Schema.Decoder<Type, DecodingServices>, but Schema exports that decode-only interface as ConstraintDecoder, so generated clients failed to compile ('"effect/Schema"' has no exported member named 'Decoder'). The emitted helper now uses Schema.ConstraintDecoder.
