Nameplate 0.1.0

• Initial release: frame, name tag, watermark, and connect-splash overlays with per-host default colors.
• Status menu doubles as a dashboard: uptime, IP address (click to copy), CPU load, RAM, free disk, and layer toggles.
• Frame corner rounding is configurable per corner (radius slider + corner toggles); default rounds only the bottom corners.
• Agent skill for attention alerts ships in skills/nameplate-attention/.
• Decoration visibility mode: show frame/tag/watermark/splash always, or only when viewed remotely (virtual display detected or Screen Sharing/VNC connected); attention alerts are exempt.
• Native grouped settings (System Settings style): Identity, Layers, Splash, General, and About panes with a live preview.
• Fleet file support (~/.config/nameplate/fleet.json) to brand every Mac from one synced dotfile.
• Bundled nameplate CLI: attention (topmost message card + pulsating borders for agents that need the human), splash, and settings.
• Sparkle auto-updates for Developer ID release builds (disabled for dev and Homebrew installs).
• Designed app icon: dark glass screen with a glowing jade frame and nameplate pill.
• Start at login, menu bar name toggle, hideable menu bar icon, and nameplate://splash URL scheme.
