Prompt: Update Sitemap

Update _pages/sitemap.md to reflect changes in the repository.

Steps

Check for new/modified/removed content in:
- _pages/ - Pages
- _posts/ - Blog posts
- _projects/ - Projects
- _publications/ - Publications
- _experience/ - Work experience
- _education/ - Education
Also check for any new directories added to the root that may contain content (e.g., _talks/, _teaching/, _portfolio/, etc.).
Review _pages/sitemap.md and update to match current repository structure:
- Add/remove/modify sections as needed
- Update the Main Pages table with new pages and descriptions
- Add collection loops for any new directories found
- Maintain consistent formatting
If new directories are found, ask the user:
- Should this directory be included in the sitemap?
- What section title should be used?
- What description should be added?
Verify all links use Jekyll templating: ``
