/**
 * Extended createBitbybitDevOcct that uses CDN-hosted WASM file by default.
 * This has the same interface as the original createBitbybitDevOcct but
 * automatically configures locateFile to use the CDN for WASM loading.
 * 
 * This is designed for browser/webworker usage where bundling the WASM
 * is problematic (e.g., with webpack).
 *
 * @param moduleOverrides - Emscripten module configuration options
 * @returns Promise that resolves to the initialized OCCT module
