Add Zerobyte installer, CT script, and docs

Introduce Zerobyte support: add LXC container installer (install/zerobyte-install.sh), container template/update script (ct/zerobyte.sh), and frontend metadata (frontend/public/json/zerobyte.json). Update docs (docs/AI.md) to require explicit "tarball" mode for fetch_and_deploy_gh_release, add helper notes and best-practices, and include a new get_latest_github_release usage. Also switch the shellscript formatter in .vscode/settings.json to foxundermoon.shell-format. The installer fetches required binaries (restic, rclone, shoutrrr), installs Bun, builds Zerobyte, configures a systemd service, and prepares runtime directories and env config.
