Rewrite kernel and double exception handlers to save EXCCAUSE/EPC1 to RTC STORE registers before triggering a software reset, replacing the LED-blink diagnostic with post-mortem debug info that survives reset. Add user exception dispatch in the level-1 handler with a weak espradio_user_exception symbol so programs without espradio still link. Implement procPin/procUnpin for Xtensa using RSIL/WSR PS to properly disable interrupts during atomic operations. Fix abort() to use a waiti loop instead of bare spin. Add --wrap ldflags for malloc/calloc/free/realloc/ppCheckTxConnTrafficIdle to support espradio WiFi blob integration. Signed-off-by: deadprogram <ron@hybridgroup.com>
