Subject: [PATCH] Disable file logging in main process

Prevent the main process from writing logs to file when running in multi-process mode. base.ts and napcat.ts now disable file logging unless the process is a worker or multi-process mode is disabled (checks NAPCAT_WORKER_PROCESS / NAPCAT_DISABLE_MULTI_PROCESS and ENV.isWorkerProcess / ENV.isMultiProcessDisabled). This reduces duplicate log output and disk I/O by ensuring only worker processes write log files.
