feat: Add ESLint coverage for scripts/ directory (#81 follow-up)

- Add scripts/eslint.config.mjs (Node.js/CommonJS environment, flat config)
- Add eslint + @eslint/js devDependencies to scripts/package.json
- Add 'lint' script to scripts/package.json
- Extend CI lint job to run ESLint on scripts/ as well
- Fix lint issues found: unnecessary regex escapes in generate-llms-txt.js
  and split-readme.js, rename caught error var to _error in split-readme.js
