feat: Add routing replication commands for Issue #30 Phase 2

Implements advanced trace manipulation and routing pattern copying:
- Enhanced delete_trace with net-based bulk deletion and layer filtering
- Added modify_trace to change width, layer, or net by UUID/position
- Added copy_routing_pattern to replicate routing between component groups
