Config Command Array Functions

What: Removed several project-level config management functions

Removed:

• Ym1() - Add items to array config (line 439101)
• YPB() - Remove items from array config (line 439140)
• VPB() - Set config value (line 439430)
• KPB() - Delete config key (line 439488)
• FPB() - Get config value (line 439413)
• zPB() - List config (line 439507)

Reason: Config management migrated to settings.json system

Migration: Use .claude/settings.json for project configuration instead of CLI commands

Evidence: Functions at lines 439101-439507 in v1.0.128 marked as removed in diff
