Subject: [PATCH] Add support to disable multi-process and named pipe via env

Introduces NAPCAT_DISABLE_MULTI_PROCESS and NAPCAT_DISABLE_PIPE environment variables to allow disabling multi-process mode and named pipe connection, respectively. Also simplifies process termination logic by always using SIGKILL.
