CRITICAL BUG FIXES:
- [C1] IFS modification without restoration (line 390)
Problem: Changed IFS to '|' but never restored, affecting all subsequent word splitting
Fix: Save/restore IFS around read operation to prevent scope pollution
- [C2] Unprotected cd commands without error checking (5 instances)
Lines: 545, 822, 830, 845, 986
Problem: If cd fails, subsequent commands execute in wrong directory
Impact: Could corrupt system, install to wrong location
Fix: Added error checking: cd /tmp || return 1 (or handle gracefully)
IMPROVEMENTS:
- Word splitting now works correctly throughout script
- Directory changes are validated before proceeding
- Cleanup operations fail gracefully if cd fails
All syntax validated (bash -n: PASS)
