feat: KDE config 33 packages + source archival in Makefile

- Enabled kirigami (core-only, QML disabled) + kf6-kio (KIOCORE_ONLY)
  in redbear-full.toml (total 33 KDE packages: 31 KF6 + kdecoration +
  kglobalacceld + kwin + kirigami + kf6-kio)
- Plasma packages (framework/workspace/desktop), breeze, kde-cli-tools
  documented as blocked — cookbook dependency resolver bug prevents
  deps (kdecoration, kf6-extra-cmake-modules) from being scheduled
  before dependents. Remaining blockers: kf6-knewstuff/kwallet need
  KF6Attica (not in tree)
- mk/redbear.mk: 'make sources' target archives all fully-patched
  sources; hooked into 'make all' as dependency of harddrive.img
- Removed archive step from build-redbear.sh (now in Makefile)
- 210 source archives generated, 171 packages in manifest
