feat: comprehensive VS Code extension bundling optimization analysis (Issue #9)

[IanMayo]

Summary

Completed comprehensive investigation into VS Code extension bundling optimization to address CI performance warning: "This extension consists of 219 files, out of which 107 are JavaScript files. For performance reasons, you should bundle your extension."

• 📊 Analyzed current bundle composition (15,145 files, 4,342 JS files)
• 🔍 Researched and compared 3 bundling solutions (esbuild, webpack, rollup)
• 🏗️ Evaluated architecture-specific considerations for WebSocket server and custom editors
• 📋 Created detailed implementation roadmap with timeline estimates (6-11 hours)
• ✅ Provided comprehensive analysis report with actionable recommendations

Key Findings

• Recommended Solution: esbuild bundling for 10-100x faster builds with minimal configuration
• Expected Impact: Reduce from 219 files to <10 essential files (~95% reduction)
• Performance Benefits: Faster extension loading, reduced marketplace download size
• Risk Level: Low - comprehensive testing strategy provided for WebSocket and webview functionality

Deliverables

• VS_Code_Extension_Bundling_Optimization_Analysis.md - Complete analysis report
• Updated Memory_Bank.md with detailed task documentation following APM framework
• Implementation roadmap with 3-phase approach and risk mitigation strategies
• Optimized .vscodeignore recommendations for file count reduction

Test Plan
