Overview

Rewrites a gem's version requirement in the Gemfile when the user picks a version beyond the declared constraint.

Bundler's own Injector can only append or remove entries, so this performs a targeted, in-place edit of the existing gem "name", ... line, keeping any groups, options, and trailing comments intact. When no editable line is found it warns and returns false rather than risk corrupting the file.
