In the updated version I have been working on improving :  POSIX Pipelines (|): Fixed pointer bugs to successfully chain commands and stream output directly between processes. Asynchronous Jobs (&): Added non-blocking execution to allow tasks to run silently in the background. Process Management: Built a SIGCHLD signal handler to automatically reap zombie processes and prevent system leaks.   Arena Allocator: Ripped out dynamic malloc calls and replaced them with a zero-allocation static memory arena for maximum parsing speed. Hardware Telemetry: Embedded monotonic clocks to measure the exact nanosecond latency of new hot path.
