Webpack Config Validator

Validate webpack configuration files exported as JSON for structural correctness, entry/output issues, deprecated loaders and plugins, optimization configuration, and best practices. Pure Python 3 stdlib — no external dependencies.

Note: webpack configs are JS/TS, not directly parseable. This validator works with JSON-exported configs. Export via:

node -e "console.log(JSON.stringify(require('./webpack.config.js')))" > config.json
python3 scripts/webpack_config_validator.py validate config.json
