Fix build failures by adding missing dependencies and configuration

This commit fixes the build failures in PR pixie-io#104 by:

1. Adding root-level .eslintrc that extends from .config/.eslintrc
   - ESLint was unable to find configuration without this file

2. Installing missing webpack-related dependencies:
   - webpack v5 and webpack-cli (upgraded from webpack v4)
   - webpack plugins: copy-webpack-plugin, eslint-webpack-plugin,
     webpack-subresource-integrity, webpack-livereload-plugin,
     webpack-virtual-modules, fork-ts-checker-webpack-plugin
   - webpack loaders: imports-loader, sass-loader, sass, css-loader,
     style-loader, swc-loader
   - Other build tools: glob v10, tslib, @swc/helpers

3. Installing eslint-plugin-deprecation v2.0.0
   - Required by the new .config/.eslintrc configuration
   - Version 2.0.0 is compatible with ESLint 7.x

4. Updating .config/webpack/tsconfig.webpack.json:
   - Added skipLibCheck: true to skip type checking on declaration files
   - Added noImplicitAny: false to allow implicit any types

5. Updating package.json scripts:
   - Added TS_NODE_PROJECT environment variable to build and dev scripts
   - This ensures webpack-cli can properly load the TypeScript config

All CI checks now pass:
- yarn typecheck ✓
- yarn lint ✓
- yarn test:ci ✓
- yarn build ✓
- compatibility check ✓
