separates platform-specific timer and interrupt code into hal-posix-task and hal-win-task gems. mruby-task now uses HAL interface defined in task_hal.h, making it easier to port to new platforms. hal-posix-task: uses sigalrm/setitimer for timer, sigprocmask for irq protection, and SA_RESTART flag to prevent EINTR on system calls. hal-win-task: uses multimedia timer API and critical_section for irq protection. both HALs support multiple mrb_state instances with single shared timer. auto-detection loads appropriate HAL based on platform.
