Initial Go project built with Bubble Tea and Lip Gloss: - Live preview and management of /etc/update-motd.d scripts - Embedded presets (ubuntu-default, minimal, server-dashboard) - Bundled POSIX sh style scripts (brand header, sysinfo panel, footer) - Snapshot/restore safety around applying changes - CLI subcommands preview, apply, restore, list-presets - Unit tests for detect, sanitize, and apply logic
