Build me a command-line tool that acts as a super-fast "fuzzy finder." I want an interactive filter for my terminal that I can use on any kind of list: my files, my command history, running processes, git commits, you name it. The idea is that I can just start typing parts of what I'm looking for, and it will instantly show me the matching results, even if I don't type the full name correctly.

I'll need it to have good shell integrations, so it should come with key bindings for popular shells like Bash, Zsh, and Fish that can override the default ctrl-r history search. It should also include a preview pane on the side that can show the contents of a file or more info about the selected item. Also, provide plugins for Vim and Neovim. The tool should be really fast and portable, ideally as a single binary I can easily install anywhere.
