Gregory Gauthier 452051f0c1 refactor(git): improve diff handling to tolerate exit code 1
- Introduce git.Diff function that uses CombinedOutput and treats exit code 1 as success (indicating changes exist).
- Update prdescribe command to use git.Diff and trim whitespace when checking for empty diffs.
- Enhance prdescribe output to include base branch in the status message.
