/**
 * Parse CSV Uint8Array stream in Worker thread using WASM.
 * Uses Transferable Streams for zero-copy transfer.
 * Uses WASMBinaryCSVStreamTransformer for direct binary processing (no TextDecoder overhead).
 *
 * This provides non-blocking CSV parsing for large files while maintaining UI responsiveness.
 *
 * Supports both Node.js (>=20.0.0) and Browser/Deno environments.
 * Node.js 20+ supports ReadableStream transfer across worker threads.
 *
 * @internal
 * @param stream CSV Uint8Array stream to parse
 * @param options Parsing options
 * @returns Async iterable iterator of records
