Rebuilt itrogers.com on Astro

Migrated this site off Gatsby and onto Astro. The old build had drifted out of date and felt heavier than a personal site should be. Astro ships zero JavaScript by default, which is exactly right for something that’s mostly words.

Kept every article, set up 301s from the old date-prefixed URLs, and added this notes stream so the site can be a living document instead of a thing I touch once every two years.
