Got browser history searching done today. Chrome's history file is just a SQLite database so that was pretty easy to pull in.
Lots of little details related to actually fetching the date, which aren't worth talking about too much and took up most of the day. I also revamped the import pipeline a bit to reduce head-of-line blocking when some requests take a while.
With this done, the database contains about 13,000 items, and the HNSW search index takes a while to build. So I'll work on optimizing that tomorrow.
