Copyright Assignment

• This document is covered by the BSD License, and I agree to contribute this PR under the terms of the license. This is for the list submission, not for the project(s) you're adding, I don't care what license the plugins have as long as they have something.

Checklist

• I have read the CONTRIBUTING document.
• All new and existing tests passed.
• I have confirmed that the link(s) in my PR is valid.
• I have signed off my commits. You can use git commit --amend --no-edit --signoff to amend an existing commit, and you can find more details about signing off commits on the DCO GitHub action page here.
• My entries are single lines and are in the appropriate (plugins, themes, or completions) section, and in alphabetical order in their section.
• The completion/plugin/theme has a plugin file in the repository that conforms to the ZSH Plugin Standard - TLDR, there's a plugin file with a .plugin.zsh, .zsh or .sh suffix, it is not just bare instructions to be added to .zshrc
• Any added completions have a readme and a license file in their repository.
• Any added frameworks have a readme and a license file in their repository.
• Any added plugins have a readme and a license file in their repository.
• Any added themes have a screenshot, a readme, and a license file in their repository.
• I have stripped any leading and/or trailing zsh-, zsh-plugin and/or oh-my-zsh- substrings from the link's displayed name. This makes it easier to find plugins/themes/completions by name by preventing big clusters in the O and Z sections of the list.

I read the thread and fail to see why you're removing it. zi is the best documented, most feature-complete zsh plugin framework currently available. The linked thread just accuses it of looking "sus" and focuses on "oh he also works in marketing, marketing bad." The only real accusation is the initial install uses the zshell.dev homepage link instead of github (it links to github; and the source for zshell.dev is open source).

I don't have a dog in this, I've submitted an issue or two to zshell over the years but haven't contributed. This entire fake outrage just seems ridiculous and irrational.
