Simplify packaging with webpack and unified setup script

Replace complex dist.js with cleaner setup.js that builds and installs
both components as self-contained packages. Add webpack bundling for
VSCode extension to eliminate dependency warnings. Includes automatic
CLI configuration for both Claude CLI and Q CLI.

Changes:
- New scripts/setup.js for one-command development setup
- Webpack configuration for extension bundling
- Remove DOMPurify/jsdom dependencies (bundled instead)
- Auto-detect and configure available AI CLIs
- Update package.json scripts for simplified workflow

See progress in issue #1.
