a822c66f - feat(node-streams): add conditional Node stream support to instant-validation

feat(node-streams): add conditional Node stream support to instant-validation Makes instant-validation.tsx conditionally use Node.js native streams (renderToPipeableStream) instead of web streams (renderToReadableStream) when __NEXT_USE_NODE_STREAMS is enabled. This prevents hangs that occurred when instant-validation bypassed the stream API wrappers. Changes: - Remove static import of renderToReadableStream - Add conditional lazy requires for both web and Node Flight APIs - Use renderToFlightPipeableStream wrapper for Node path (handles debug channel conversion) - Handle stream iteration differences (Node Readable vs web ReadableStream.values()) - Apply pattern at both rendering call sites: collectStagedSegmentData and createCombinedPayloadStream Known limitation: - Debug channel at segment level disabled with Node streams to avoid parallel bridge issues - Combined payload level debug channel still enabled - 4/5 instant-validation tests pass; debug channel interaction needs further investigation Test results with __NEXT_USE_NODE_STREAMS + __NEXT_CACHE_COMPONENTS + __NEXT_EXPERIMENTAL_DEBUG_CHANNEL: - instant-validation-static-shells: 4 passed, 1 failing (debug channel interaction) - Without debug channel: all tests pass Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
