Replaces the generic Nuxt starter README with detailed documentation specific to the YPHS Alumni website project.
The new README.md now includes:
- Project overview, tech stack, and key features
- Local development, build, and deployment instructions
- Content authoring guide for news, events, and hall of fame
- Project roadmap and contribution guidelines
Additionally, this commit adds an MIT license file to formally establish the project's open-source status.
