ci: deploy Vite demo to GitHub Pages

[bdhyv]

Summary

• deploy the standalone Vite React SDK demo to GitHub Pages on changes to the example or SDK packages
• configure the /platform-sdk-react/ asset base and include Vite build variables in Turbo's cache key
• document the hosted demo URL
• supersede ci: deploy Storybook to GitHub Pages #296; Storybook is intentionally excluded from Pages

Setup after merge

• enable GitHub Pages with GitHub Actions as the source
• set the YVP_DEMO_APP_KEY repository variable
• register https://youversion.github.io/platform-sdk-react/ as a callback URL for that Platform app

Test plan

• pnpm --filter vite-react lint
• Pages-targeted pnpm turbo build --filter vite-react
• verify generated asset URLs use /platform-sdk-react/
• serve and load the production artifact under /platform-sdk-react/

Greptile Summary

This PR deploys the Vite React SDK demo to GitHub Pages. The main changes are:

• Adds a Pages build and deployment workflow for pushes to main.
• Validates the demo app key before building.
• Configures the /platform-sdk-react/ Vite base path.
• Adds Vite variables to the Turbo build cache key.
• Documents the hosted demo URL.

Confidence Score: 5/5

This looks safe to merge.

• The workflow now fails before deployment when the app key is missing.
• Removing the path filter ensures shared tooling changes on main trigger a fresh deployment workflow.
• No remaining blocking issue meets the scope for this follow-up review.
