RemoteExecutionEnv.listFiles resolves the path and lists through the daemon; a daemon without the listFiles feature yields not_supported. LocalExecutionEnv is NodeExecutionEnv plus listFiles through a daemon on the same machine, so local and SSH sessions list with the same code. nodePlatform maps hello's Rust names to Node's (windows -> win32, macos -> darwin, x86_64 -> x64, aarch64 -> arm64).
