feat(docs): add VitePress documentation site under /docs

[ParvikaShekhawat]

Summary

Adds a full documentation site for JSON Schema Studio, built with VitePress, hosted at studio.ioflux.org/docs — implementing the approach the team discussed and agreed on in an earlier thread (same repo, subpath hosting, no separate domain/DNS needed).

Includes:

• Full docs content: Introduction, Why JSON Schema Studio, Quick Start, Installation, Tech Stack, Understanding the Visualization, How It Works, Controls, FAQ & Known Issues, Roadmap, Contributing Guide, Versioning & Changesets
• Collapsible sidebar navigation, local search, light/dark theming matching app branding
• "Edit this page on GitHub" + last-updated timestamp on every page
• Updated the in-app "Documentation" navbar button to link to /docs instead of the GitHub README
• Updated deploy.yml to build the docs site and merge it into dist/docs/ before the existing GitHub Pages deploy step (no other workflow steps changed)
• Added docs:build / docs:dev convenience scripts to the root package.json
