Summary

This PR modernizes the project's linting configuration by migrating from the deprecated .eslintrc.json format to ESLint's new flat config format (eslint.config.mjs), and updates development dependencies to their latest versions.

Key Changes

ESLint Configuration Migration: Converted from .eslintrc.json to eslint.config.mjs using the flat config format
- Removed deprecated ESLint plugins (eslint-plugin-github, eslint-plugin-jest, eslint-plugin-prettier)
- Simplified rule configuration to focus on core TypeScript linting rules
- Moved ignore patterns into the config file itself (removed .eslintignore)
Development Dependencies Updated:
- @typescript-eslint/eslint-plugin: ^5.62.0 → ^8.58.1
- @typescript-eslint/parser: ^5.62.0 → ^8.58.1
- eslint: ^8.57.0 → ^10.2.0
- @types/jest: ^29.5.12 → ^30.0.0
- jest: ^29.7.0 → ^30.3.0
- jest-circus: ^29.6.4 → ^30.3.0
- prettier: ^2.6.2 → ^3.8.1
- ts-jest: ^29.1.2 → ^29.4.9
- typescript: ^5.4.5 → ^5.9.3
- Removed eslint-plugin-jest and eslint-plugin-prettier dependencies
Jest Configuration: Removed deprecated testRunner: 'jest-circus/runner' option (jest-circus is now the default)
Lint Script: Updated from eslint src/**/*.ts to eslint src/ for broader coverage

Implementation Details

The new flat config format provides better composability and is the recommended approach for ESLint v9+. The configuration maintains the same TypeScript linting rules while removing GitHub-specific and formatting-related plugins that are no longer needed in the project's workflow.
