Automate microsite deployment with build script and GitHub Actions

[Copilot]

The microsite at /docs/index.html required manual synchronization with the main application code whenever badge generation or sorting logic changed, creating maintenance burden and drift risk.

Changes

Build System

• scripts/build_microsite.py: Generates docs/index.html from template, injecting commit hash
• docs/index.template.html: Source template with {{COMMIT_HASH}} placeholder (tracked in git)
• docs/index.html: Now generated during deployment (excluded from git via .gitignore)

Deployment Pipeline

• .github/workflows/deploy-pages.yml: Builds and deploys to GitHub Pages on push to main
• Triggers on changes to docs/**, badgesort/**, or build scripts
• Supports manual dispatch

Documentation

• docs/BUILD_SYSTEM.md: Architecture, sync checklists for keeping CLI/microsite algorithms aligned
• docs/README.md: Build and deployment workflow
• README.md: Live site link at https://chipwolf.github.io/BadgeSort/

Result

<!-- Deployed site now shows build information -->
<p>Build: <code>467e2a8</code></p>

Microsite automatically rebuilds and deploys on every push. Commit hash visible on live site for version transparency.

Setup Required

Repository Settings → Pages → Source: "GitHub Actions" (not branch-based)

This section details on the original issue you should resolve

<issue_title>Deduplicate code between BadgeSort and the microsite</issue_title>
<issue_description>Currently the program is in /badgesort and our microsite is in /docs

We use the python from the app in the microsite

However, when we update the app we need to manually sync those changes into the microsite

Write a replacement GitHub action to deploy the GitHub pages site that grabs the latest version of the code so we only keep one copy in the repo

You may need to work out what the differences are between the code in the microsite and the actual BadgeSort code and the site may need some kind of wrapper, but perhaps not.

Make sure the site shows the commit hash somewhere too</issue_description>
