delta-io

Scaffolds a new Delta Lake blog post under `src/content/blog/`. Guides the user through generating a URL-safe dated slug directory, front matter (title, description, thumbnail, author, publishedAt) matching the schema in `src/content.config.ts`, optionally creating new author profiles under `src/content/profiles/`, and pasting/grammar-checking initial content. Use when the user says "new blog post", "create a blog", "delta blog", "scaffold a post", or asks to add a post under `src/content/blog`.
