Build me a lightweight terminal app for browsing and querying databases.

I want it to feel fast and keyboard friendly, with vim style navigation and mouse support too. It should let me connect to a database from a URL or connection settings, then browse schemas and tables, open table details, and run SQL in a built in editor with syntax highlighting. I also want query history, a way to save favorite queries, and simple shortcuts for copying data, filtering rows, and switching between schemas without a lot of clicking around.

Make it work nicely in a normal terminal with a clean text UI, and keep it cross platform if possible. Support Postgres first, then MySQL and SQLite at least, and make it easy to add other databases later. If you need to, look up the current docs for any tricky database client setup.
