bug-fix release.
- fix: boss-fight freeze — a leaked stderr→/dev/null redirect made every later prompt invisible so the game looked hung
- fix: corrupt profile version / scores no longer wedge or crash the game (validated, fail-safe)
- fix: no CPU spin on closed stdin; F9 no longer misread as a paste; counted vi p/P repeat correctly
- fix: dropped invalid
ping --countandssh -DNanswers; corrected getfattr manpage; tighter "save ls output" grading - fix: New Game fully clears progress
- requires bash 4.4+
