This pull request introduces a variety of changes, including the addition of mock implementations for testing, updates to existing component mocks, new test cases for components, and improvements to test assertions and styling checks. Below is a categorized summary of the most important changes:

Mock Implementations for Testing

• Added mock implementations for jQuery and jQuery UI to facilitate testing, including specific mocks for autocomplete functionality (__mocks__/jquery.js, __mocks__/jquery-ui.js, __mocks__/jquery-ui/ui/widgets/autocomplete.js). [1] [2] [3]

Component Updates

• Refactored the MockFooter component to include a more detailed structure and updated its mock content to reflect the HackRPI branding (__tests__/__mocks__/mockRegistry.tsx).

New Component Tests

• Added comprehensive tests for the EventCard component, including functionality for editing, deleting, and toggling visibility of events (__tests__/components/EventCard.test.tsx).
• Introduced tests for the Game Board component to validate grid rendering, value display, and structural styling (__tests__/components/game/board.test.tsx).
• Added tests for the Game Tile component to verify rendering of different values and corresponding styles (__tests__/components/game/tile.test.tsx).

Improvements to Existing Tests

• Enhanced assertions in the AboutUs component tests to improve robustness, including checks for partial matches and updated styling expectations (__tests__/components/about-us.test.tsx). [1] [2]
• Updated Footer component tests to verify new gradient styling and layout classes (__tests__/components/footer.test.tsx).
• Adjusted Event Page tests to remove an invalid expectation for the Footer component, which is no longer rendered in the page (__tests__/components/event.test.tsx).

This pull request includes several changes across workflows, pre-commit hooks, mock files, and test files. The most significant updates involve removing the linting job from the GitHub Actions workflow, enhancing pre-commit checks, introducing mock implementations for testing, and updating test cases for improved accuracy and coverage.

Workflow and Pre-commit Updates:

• .github/workflows/nextjs.yml: Removed the lint job entirely, simplifying the CI pipeline. The build job now directly depends on the changes job instead of lint.
• .husky/pre-commit: Replaced individual TypeScript, Prettier, and ESLint checks with a unified lint-staged command for pre-commit hooks to streamline code validation.

Mock Implementations for Testing:

• __mocks__/jquery-ui.js, __mocks__/jquery-ui/ui/widgets/autocomplete.js, and __mocks__/jquery.js: Added mock implementations for jQuery and jQuery UI components to facilitate testing without relying on external libraries. [1] [2] [3]

Test Enhancements:

• __tests__/components/EventCard.test.tsx: Introduced comprehensive tests for the EventCard component, covering editing, updating, visibility toggling, and deletion functionalities.
• __tests__/components/about-us.test.tsx and __tests__/components/event.test.tsx: Updated assertions for theme descriptions, banner styles, and layout components to improve test accuracy and robustness. [1] [2] [3]

Style and Configuration Changes:

• .prettierrc: Added a new jsxSingleQuote configuration option to enforce double quotes in JSX attributes.
• __tests__/components/footer.test.tsx: Updated footer component tests to check for new gradient styles and layout classes.
