chore: Migrate ESLint to v9 flat config format

Created new eslint.config.mjs with flat config:
- Migrated from .eslintrc.js to eslint.config.mjs
- Added globals package for Node.js and Jest globals
- Configured TypeScript parser and plugins
- Maintained all existing rules and Prettier integration

ESLint now running successfully with v9 flat config.

Note: 39 unused variable warnings found - these are minor code
quality issues that can be addressed in a separate cleanup PR.
