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
