feat(ags-v3): desktop adaptation — ultrawide scaling, brain power panel, system stats

- Scaling 16px base pour ultrawide 3440x1440
- Bar: CPU/RAM/GPU visible, media single player (skip playerctld), network tooltip LAN/WAN IPv4
- Volume: class module pour sizing cohérent
- Battery: désactivé (PC fixe)
- Clock: tooltip calendrier + uptime
- BrainPower: panel enrichi (focus, session, intentions, todos, repos git, derniers commits)
- App: BrainPower sur moniteur principal uniquement
- Heartbeat: Layer.TOP pour compatibilité COSMIC
