Add IronClaw container templates and install scripts (ct/ironclaw.sh, install/ironclaw-install.sh, json/ironclaw.json) to provide automated setup, service unit, and default config for the IronClaw AI agent.
Refactor tools/addon/cronmaster.sh to use the ProxmoxVE misc endpoints, initialize optional telemetry, improve function loading, and strengthen OS detection (Debian/Ubuntu-only). Make service and install behaviors more robust: ensure /usr/local/bin persistence, create/update the update script from the new repo URL, change systemd WantedBy to multi-user.target, enable service quietly, save generated credentials to /root/cronmaster.creds, and use distinct exit codes for unsupported/invalid states. Misc license URL fix and other small reliability improvements.
