docs(research): break the two worst wall paragraphs

The chezmoi overview was one 488-character sentence-block; the git-crypt mechanism and verdict

same in an editor as they do rendered.

 ## Overview
 
-**chezmoi** is a Go-binary (MIT license, 21k+ GitHub stars) that manages dotfiles across diverse machines by declaring desired state in a source directory and applying the delta to the target directory. It is the only dotfiles tool in the [dotfiles comparison table][comparison] that provides private files, whole-file encryption, password-manager integration, template-based machine-to-machine differences, partial-file management, and symlink differences — all in a single distribution.
