docs: improve README with comprehensive documentation

[Mechack08]

Description

This PR significantly improves the README documentation to make it more helpful for new contributors and developers.

Changes Made

• Add project overview and purpose
• Add installation instructions for npm and Nix
• Document all available scripts with descriptions
• Add project structure overview
• Include contributing guidelines and workflow
• Add technology stack information
• Include useful links and resources

Motivation

The current README was minimal and only included Nix development setup. This made it difficult for new contributors to:

• Get started with development using npm/yarn
• Know what commands are available
• Understand the project structure

Benefits

✅ Easier onboarding for new contributors
✅ Better discoverability of project features
✅ Clear contribution guidelines
✅ Improved project professionalism

Testing

• Verified npm install works correctly
• Verified npm start launches the development server
• Confirmed all links in README are valid
• Tested local development workflow

Type of Change

• Documentation update
• Dependencies update (package-lock.json)

Checklist

• Documentation follows markdown best practices
• All sections are clear and well-organized
• Links are valid and working
• Package-lock.json updated with latest dependencies

Thanks for this! Made some minor tweaks, mainly because I don't want to be providing npm support for when things go wrong. I also patched the remaining vulnerabilities since it's touching the lock file. I'm going to close this, re-open on the fork and merge so I can fix the broken workflow.
