Synthetic Sagas

Since last time, I've been continuing to rewrite my janky little text editor from scratch with a lot of ai assistance. This started out as a learning project, but recently I switched to actually using the new editor because it's less janky and more featureful than the old version. Contrary to last time, I'm now often just committing ai-generated code after a little manual testing ...
