* feat: support process write callback and encoding args - Lower static stdout and stderr writes with encoding and callback overloads. - Schedule completion callbacks through the next-tick queue in C and LLVM builds. - Cover encoding aliases, ordering, and async-free refusal behavior. * fix: handle omitted process write arguments
