junegunn/fzf.vim ? reverse-engineered prompt

Build me a Vim plugin that adds a bunch of handy fuzzy finder commands on top of fzf.

I want to be able to search files, git files, open buffers, recent files, command history, search history, marks, jumps, windows, tags, commits, and lines from the current file or all open files, all from simple Vim commands. It should feel native in both Vim and Neovim, with smart defaults, keyboard shortcuts for opening results in a split, vertical split, or new tab, and an option to insert selected results into the current buffer instead of opening them.

Please include nice preview support when available, and make the commands easy to customize with a global config. It should also work well with common tools like ripgrep, ag, bat, delta, ctags, and fugitive when they are installed, but still be usable without everything. If needed, look up current docs online so the setup and command names match the real fzf Vim integration.
