Export Aaron Gustafson archive posts to Markdown

[Copilot]

This change adds a complete Markdown export for every post in archives/ authored by Aaron Gustafson. Each export follows the requested filename/frontmatter conventions and preserves post bodies while relocating locally hosted images into the export tree.

• Scope

  • Added export/ at the repository root
  • Exported 147 Aaron Gustafson archive posts as Markdown
  • Named files as YYYY-MM-DD-post-slug.md

• Frontmatter normalization

  • Added core fields for each post:
    • title
    • date
    • comments
    • tags
  • Included description where derived from post content
  • Added permalink back to the original archive URL

• Content preservation

  • Preserved post bodies as-is, including raw HTML, embeds, figures, and inline markup from the archive pages
  • Kept original tag capitalization and empty-tag cases intact (tags: [] where applicable)

• Local asset export

  • Copied locally referenced images into export/images/<post-slug>/
  • Rewrote image references in exported Markdown to point at the copied assets
  • Left remote image URLs untouched

Example exported frontmatter shape:
