macOS Terminal – Truecolor support

As CLI tools become more sophisticated, more of them are requiring Truecolor support.

Here's an example within the helix-editor/helix repository https://github.com/helix-editor/helix/wiki/Troubleshooting#rendering-issues-on-macos-terminal

Here's a list of Terminal apps that do not support Truecolor https://gist.github.com/XVilka/8346728#not-supporting-truecolor

Terminal.app does not support Truecolor, and it is forcing users to switch to competing options like Kitty / iTerm2.

I would like to request that Terminal.app implement Truecolor support so we can continue using it as a modern CLI tool.
