Bash-it/bash-it ? reverse-engineered prompt

Build me a community style Bash setup toolkit for people who live in the terminal and want their shell to feel more powerful without hand editing a huge bashrc. I want an easy install script that clones into something like a hidden home folder, updates or creates the user’s Bash config safely, and makes a backup first. It should let people turn on useful aliases, tab completions, plugins, prompt themes, and their own custom scripts and functions. Add a simple command line helper so users can search available components, enable or disable them, and get help.

Please also include a doctor style diagnostic command that prints environment info, Bash version, where the config is loaded from, what components are enabled, and whether the install looks healthy. It should mostly work on Bash 3.2 and up, while gracefully skipping features that need newer Bash. Include uninstall support and clear docs so someone can get started fast and customize it later. If you need details, check current docs online.
