Split Rust program compilation so code generation and assembly finish before the main thread materializes GC-backed executable objects. The new CompiledProgram handle owns the parsed program, generator state, and bytecode until C++ consumes it on the main thread. Wire WebContent script fetching through that handle for classic scripts and modules. Syntax-error paths still return ParsedProgram, so existing error reporting stays in place. Successful fetches now do top-level codegen on the thread pool before deferred_invoke hands control back to the main thread. Executable creation, SharedFunctionInstanceData materialization, module metadata extraction, and declaration data extraction still run on the main thread where VM and GC access is valid.
