Workstation optimization: Chrome cleanup, package purge, PCIe audit, service tuning
- 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 - D-Bus cleanup: removed stale org.kde.kwalletd6.service stub - Ansible: all changes reflected in vars/main.yml and task files
