Adding SQLite with Claude Code

[tebba-von-mathenstein]

I'm satisfied with these changes, but I'm opening this pull request to potentially share with students and others to demonstrate a real concrete example of how well these tools now work.

This PR changes the save mechanism from a kinda clunky filesystem based approach with a text file and an image to a SQlite based approach. I had Claude do 3 main things, I made very light edits to the produced code. I asked Claude to make the updates iteratively, and made those changes after each iteration rather than letting Claude run a long time. The update:

1. Change the final prompt to specify a JSON format rather than free form text, so Claude produces something that can be used more programmatically later.
2. Creates a SQlite schema with a single table that records the parameters, prompts, and image.
3. Update the script so it saves to that format instead of the filesystem
4. Create a second script that allows folks to scan the database in the terminal, and display the images for a specific run.
