wangjianyu3 6a1b2c6903 system/nxrecorder: Fix null pointer dereference in argument parsing 
When a command has no arguments (e.g., 'q', 'quit', 'stop'), the strtok_r()
function returns NULL for the arg parameter. The argument trimming loop was
dereferencing this NULL pointer without checking, causing undefined behavior
and system hang on ESP32-S3.

This commit adds a null check before dereferencing the arg pointer in the
leading space trimming loop.

Tested on ESP32-S3 (lckfb-szpi-esp32s3) - quit command now works correctly.
