Xemptuous/sqlua.nvim ? reverse-engineered prompt

Build me a NeoVim plugin that feels like a simple SQL IDE inside the editor. I want to open a command like :SQLua, see a sidebar with my database connections, browse tables and schemas, and quickly switch which database is active. It should let me run the whole buffer or just selected SQL, and show the results in a separate pane. I also want a way to edit my saved connections from inside NeoVim, plus keep per database query files around so I can store reusable SQL snippets.

It should support the common databases like PostgreSQL, MySQL, MariaDB, SQLite, and Snowflake, using the right command line tools if needed. Please make it fast, simple, and useful out of the box, with sensible default keybinds and a clean UI that fits NeoVim. If anything current changes in the ecosystem, look up the latest docs online before implementing.
