Improved Alias Detection Logic

What changed: Shell alias detection now preserves custom user configurations How it works:

• Only removes/replaces aliases pointing to the default Claude installation path
• Preserves custom aliases pointing to other locations
• Shows "Custom claude alias found" message when detected
• Displays "Keeping your existing alias configuration" to inform users

Details:

• Enhanced regex pattern allows flexible whitespace: /^\salias\s+claude\s=/ (line 377702)
• Function jk1() at line 377711 parses alias values and compares against default path
• Previous version V11() at line 377695 in v1.0.112 removed all claude aliases indiscriminately
• Evidence: Compares alias target against zv (default path) at line 377718
