Summary
This PR modernizes the project's linting configuration by migrating from the deprecated
.eslintrc.jsonformat 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.jsontoeslint.config.mjsusing the flat config formateslint-plugin-github,eslint-plugin-jest,eslint-plugin-prettier).eslintignore)Development Dependencies Updated:

testRunner: 'jest-circus/runner'option (jest-circus is now the default)Lint Script: Updated from
eslint src/**/*.tstoeslint src/for broader coverageImplementation 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.
