Subject: [PATCH] fix(worker): default logdir to /tmp when -l not given
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

logdir was NULL without -l flag, causing stat(NULL)/mkdir(NULL) → EFAULT.
Set default to /tmp after argument parsing, before directory creation.
