new-promoted

Create a new promoted/featured card in the src/content/promoted/ directory.

Steps

1. Take the title from the user's argument. If not provided, ask for one.
2. Generate a kebab-case filename from the title.
3. Read existing promoted items in src/content/promoted/ to determine the next order number (highest existing order + 1, or 1 if none exist).
4. Ask the user for:
   • Description — keep under 120 characters
   • Link URL — destination when the card is clicked
   • Link text — CTA button text (e.g., "Learn more", "View project")
   • Image URL — card image
5. Create src/content/promoted/<slug>.md:

---
title: "<title>"
description: "<description>"
image: "<image URL>"
link: "<link URL>"
linkText: "<link text>"
order: <next order number>
publishedAt: <today's date YYYY-MM-DD>
---

6. Tell the user:
   • The file was created at src/content/promoted/<slug>.md
   • The order field controls display order on the homepage (lower = first)
   • Keep title under 60 characters and description under 120 characters
   • All fields are required for promoted cards
