This pull request introduces significant improvements to the project's frontend infrastructure, developer workflow, and code organization. It adds automated dependency management and CI/CD workflows, updates dependencies, and refactors routing and UI for better maintainability and user experience.

CI/CD and Dependency Management Enhancements:

• Adds Dependabot configuration for automated dependency updates for both npm and GitHub Actions, including grouping and labeling strategies for easier review. (.github/dependabot.yml)
• Introduces GitHub Actions workflows for automated deployment to Vercel on main branch changes and for comprehensive PR checks including linting, type checking, testing, code formatting, security audits, and Copilot PR review. (.github/workflows/deploy.yml, .github/workflows/pr-checks.yml) [1] [2]

Frontend Dependency Updates:

• Updates the baseline-browser-mapping package to version 2.9.18 in both package.json and package-lock.json, and removes unused or optional dependencies such as bare-url, bufferutil, and utf-8-validate to keep the dependency tree clean. [1] [2] [3] [4] [5] [6]

Frontend Routing and Component Refactoring:

• Refactors the main app routing to use a Layout component and introduces protected routes for onboarding, status, scanning, challenges, and proofs, improving separation of concerns and user flow. (frontend/src/App.tsx) [1] [2]

UI and Style Cleanup:

• Removes all custom CSS and theme variables from App.css to avoid conflicts with the design system defined in index.css. (frontend/src/App.css)

UI Consistency and Logging:

• Updates button and label styles in the ChallengeScanner component to use new color tokens and font classes for a more consistent and branded UI. Also standardizes logging output by removing emoji prefixes from log messages. (frontend/src/components/ChallengeScanner.tsx) [1] [2] [3] [4] [5] [6]
