Fix GitHub Pages deployment conflicts by preventing Jekyll processing of Hugo site

[Copilot]

Problem

The repository was experiencing deployment conflicts due to GitHub's automatic "pages-build-deployment" action trying to process the Hugo site with Jekyll. This caused build failures with errors like:

Liquid Exception: Invalid Date: '"{{ .Date }}"' is not a valid datetime.
ERROR: YOUR SITE COULD NOT BE BUILT

The issue occurred because:

• GitHub Pages was configured to deploy from a branch (triggering automatic Jekyll processing)
• Jekyll cannot parse Hugo template syntax like {{ .Date }}
• The custom Hugo workflow was working correctly, but the automatic deployment was interfering

Solution

This PR implements the minimal file-based changes needed to resolve the conflict:

1. Added .nojekyll file

An empty .nojekyll file in the repository root tells GitHub Pages not to process the site with Jekyll, preventing template syntax conflicts.

2. Added documentation

Created GITHUB_PAGES_CONFIG.md with clear instructions for the required repository settings change:

## Required Configuration
1. Go to Settings > Pages in the GitHub repository
2. Under Source, select "GitHub Actions" instead of "Deploy from a branch"
3. Save the changes

Impact

• ✅ Hugo workflow: Continues working perfectly (verified with test build)
• ✅ Jekyll conflicts: Eliminated by .nojekyll file
• ✅ Zero downtime: Changes don't affect existing deployments
• 🎯 Complete solution: When combined with the repository settings change, will fully disable the conflicting automatic deployment

Manual Action Required

To complete the fix, the repository owner needs to change the GitHub Pages source from "Deploy from a branch" to "GitHub Actions" in the repository settings. This will disable the automatic "pages-build-deployment" action and rely solely on the working Hugo workflow.

The changes in this PR are minimal, surgical, and preserve all existing functionality while providing a clear path to resolve the deployment conflicts.
