Krzysztof kuhy Rudnicki db6276b3ff refactor(linux_configuration): move remaining dirs + scripts/ to meta/
- Move fresh-install/ → scripts/single_use/fresh-install/
- Move hosts/ → scripts/periodic_background/hosts/
- Move i3-configuration/ → scripts/periodic_background/i3-configuration/
- Delete linux_configuration/LaTeX/, nix-poc/, report/ (dead dirs)
- Move repo-root scripts/ → meta/scripts/
- Update root .pre-commit-config.yaml: scripts/ → meta/scripts/ (9 entries)
- Update run.sh ARTIFACT_INIT_SCRIPT to meta/scripts/
- Update fresh-install/main.sh: hosts/install.sh + i3-configuration/install.sh paths
- Update check_python_location.sh: add meta/scripts/ to exception list
- Fix midnight flakiness in test_recent_workout_returns_true: use timezone-aware
  local noon instead of now-1h to avoid SQL date() boundary issues
