fix: create log file with proper permissions during systemd install #37

The install script now creates /var/log/agent-manager.log with proper
ownership and permissions before starting the service. This prevents
the "EACCES: permission denied" error that occurred when the service
tried to create the log file on first startup.

Changes:
- install.sh: Create log file and set ownership to service user
- uninstall.sh: Document that log file is not automatically removed
