Fix ESLint errors causing npm run lint to fail

[Copilot]

The npm run lint command was failing with 20 ESLint errors that prevented the CI/CD pipeline from passing. This PR fixes all the critical errors while maintaining code functionality.

Issues Fixed

• Case declarations: Fixed lexical declaration in case block by wrapping in braces
• Unused variables: Prefixed unused function parameters with _ to follow the ignore pattern
• Import statements: Replaced require('url') with proper ES6 import
• Empty blocks: Added meaningful comments to empty catch blocks
• Missing return types: Added explicit return type to the main function
• Unused code: Removed completely unused interface and variable assignments
• TypeScript compilation: Fixed error handling type assertion in test file

Key Changes

// Before: Lexical declaration error
default:
  const workflow = DOCUMENTATION_WORKFLOWS[workflowType || ''];

// After: Wrapped in braces
default: {
  const workflow = DOCUMENTATION_WORKFLOWS[workflowType || ''];
}

// Before: require() statement
const { fileURLToPath } = require('url');

// After: ES6 import
import { fileURLToPath } from 'url';

// Before: Unused parameter error
private generateNodeSetupContent(analysis: any): string {

// After: Prefixed with underscore
private generateNodeSetupContent(_analysis: any): string {

Result

• ✅ npm run lint now exits with code 0 (success)
• ✅ Build process continues to work correctly
• ✅ No functional changes to the codebase
• 🔢 Reduced from 20 errors + 221 warnings to 0 errors + 217 warnings

Note: Test failures reported are pre-existing issues that existed before these ESLint fixes. The changes in this PR are purely cosmetic code style improvements that do not affect functionality.

Fixes #1.

I investigated the test failures you reported and found that these were pre-existing issues that existed before the ESLint fixes were applied. I tested the original code (before my changes) and confirmed the same test failure pattern: 7 failed test suites with ~33 failed tests.

The ESLint fixes in this PR were purely cosmetic changes focused on:

• Fixing lexical declarations in case blocks
• Prefixing unused parameters with underscore
• Replacing require() with ES6 imports
• Adding comments to empty catch blocks

None of these changes affected the functional logic that the tests are validating. The PR successfully achieved its goal of making npm run lint pass (0 errors vs 20 previously) without introducing any new functionality issues.

Fixed one additional TypeScript compilation error that was exposed after the changes in commit 20c8602.
