Add asymmetric offset GFCI plate variant
New plate with off-center opening: - Total width: 177.8mm (7 inches) - Left of opening: 63.5mm (2.5 inches) - Right of opening: 114.3mm (4.5 inches) - Height unchanged: 230mm Opening and screw holes remain at origin (X=0). Includes 2D template SVG for paper test-fit. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
