v1.2.9

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 --count and ssh -DN answers; corrected getfattr manpage; tighter "save ls output" grading
• fix: New Game fully clears progress
• requires bash 4.4+
