restore lost packages from 0.2.3 + fix overwritten 0.2.4 files
- Restore 29 recipe symlinks (libdrm, qtbase, dbus, sddm, pipewire, etc.) - Restore 33 patches (KDE, libdrm, mesa, pipewire, sddm, wireplumber) - Restore 20+ local/scripts (audit, lint, test, build helpers) - Restore src/cook/scheduler.rs, status.rs, gnu-config/ - Restore scripts/patch-inclusion-gate.sh, run_mini1.sh, validate-collision-log.sh - Recover TLC source from HEAD (was overwritten by 0.2.3 checkout) - Recover 11 local/docs plans from HEAD (were overwritten) - Recover qt6-wayland-smoke symlink from HEAD - Fix MOTD: remove garbled ASCII art, use clean text - Update version: 0.2.0 -> 0.2.4 in os-release, motd, config - Reduce filesystem_size: 1536 -> 512 MiB - Add ABSOLUTE RULE to AGENTS.md: never delete/ignore packages - Reduce pcid scheme log verbosity: info -> debug
