feat: optimize extension packaging with webpack

- Add webpack bundling to reduce extension size from 490 files (1.12MB) to 38 files (174KB)
- Update .vscodeignore to exclude unnecessary development files
- Configure webpack with TypeScript loader and production optimization
- Update package.json scripts for webpack-based build process
- Simplify CI pipeline to remove extension packaging step
- Add webpack dependencies: ts-loader, webpack, webpack-cli

Performance improvements:
- 92% reduction in file count (490 → 38 files)
- 85% reduction in package size (1.12MB → 174KB)
- Better startup performance and loading times
