fix: resolve ESLint configuration and linting errors

- Fix ESLint extends syntax to use 'plugin:@typescript-eslint/recommended'
- Add argsIgnorePattern to ignore unused parameters starting with underscore
- Fix no-case-declarations errors by wrapping case blocks in braces
- Auto-fix prefer-const issues in UrlProcessor.ts
- All linting errors resolved, only warnings remain
