Fix: Remove 'local' keyword from global scope in malware-scanner.sh (CRITICAL)

CRITICAL FIXES:
- Line 1602: Remove 'local' from escaped_paths variable (global scope)

Issue: 'local' keyword can only be used inside function definitions.
Line 1602 is at global script scope (main execution body before main() function
at line 2542). Using 'local' in global scope causes 'local: can only be used
in a function' runtime error and script failure.

RESULTS:
- 1 CRITICAL issue fixed
- All CRITICALs now resolved (0 remaining)
