Port backend to ESM and Vitest with simplified business logic

✨ Enhancement 🧪 Tests

Walkthroughs

Description

• **Comprehensive ESM migration**: Converts entire backend codebase from CommonJS
  (require/exports) to ES modules (import/export) with .js file extensions throughout
• **Vitest adoption**: Migrates backend tests from Mocha to Vitest with updated syntax (arrow
  functions, describe.skipIf()/it.skipIf() for conditional skipping, removal of this.timeout())
• **Simplified business logic**: Removes author attribution tracking, maintenance window scheduling,
  Node version checks, email notifications, and complex filtering pipelines across multiple modules
• **Enhanced type safety**: Adds TypeScript type annotations, improves function signatures with
  nullable/optional parameters, and adds type assertions for complex scenarios
• **Module bridging**: Implements createRequire bridges and dynamic imports for lazy-loading
  optional dependencies and handling circular dependencies
• **ESM polyfills**: Adds __filename and __dirname polyfills using import.meta.url for test
  utilities
• **Backward compatibility**: Maintains compatibility through default exports, re-export aliases,
  and namespace imports where needed
• **Updater refactoring**: Simplifies version checking to focus on vulnerability detection, removes
  maintenance window logic, and updates comparison functions (isMajorBehind, isVulnerable)
• **Test cleanup**: Removes obsolete test suites (CJS compatibility tests, email notification tests)
  and refactors remaining tests for Vitest patterns
