- Chrome/Chromium cleanup (ADR 0006): removed 10GB chromium profile, broken PWA
  shortcuts, dead BROWSER_CDP_URL from .bashrc, restored Wayland chrome-flags.conf
- Package cleanup (ADR 0007): Tier 1-4 executed, 40 packages removed (KDE Plasma,
  ruby, love, xorg-server, kscreen/kscreenlocker), 45 cascade orphans purged
- Waybar USB module: auto-mount via udisks2, yazi integration, hover details
- Service tuning: disabled bluetooth.service, NetworkManager-wait-online.service
- hypridle fix: upgraded sdbus-cpp 2.3.0->2.3.1-1 (SEGV crash loop resolved)
- PCIe audit: GPU in wrong slot (PCIEX4 vs PCIEX16), 8x bandwidth loss documented
