 * Generate a deployable Cloudflare Worker bundle from compiled WASM.

 * - `worker.js` — ES Module Worker entry point with all host imports inline
 * - `program.wasm` — the compiled WASM binary
 * - `wrangler.toml` — Wrangler v3 configuration
 *
 * Host functions in worker.js are derived from the ALL_BUILTINS registry at
 * generation time, matching CloudflareHostAdapter's behavior:
 * - Crypto: returns empty strings (async Workers crypto.subtle unusable in sync)
 * - HTTP: returns structured Result<String,String> Err values
 * - IO: returns structured errors (KV is async)
 * - env: reads from Workers environment bindings
 *
 * @param wasm - Compiled WASM binary (Uint8Array from codegen)
 * @param config - Worker configuration
 * @returns ScaffoldResult with the bundle or an error
