chore(D5-3C): pre-launch doc/script cleanup

- docs: remove ghost path .github/instructions/sopify.instructions.md
  (actual install target is .github/copilot-instructions.md)
- install.sh: add python3 → python → py -3 fallback chain (align with install.ps1)
- tests: delete ~compare dead tests (command removed, 656 tests pass)
- tasks.md: mark 3.11/3.12/3.15 done, skip 3.14 (script exists)
