Git and VCS

Part of src/cmds/ — see also docs/contributing/TECHNICAL.md

Specifics

git.rs uses trailing_var_arg = true + allow_hyphen_values = true so native git flags (--oneline, --cached, etc.) pass through correctly
Auto-detects --merges flag to avoid conflicting with --no-merges injection
Global git options (-C, --git-dir, --work-tree, --no-pager) are prepended before the subcommand
Exit code propagation is critical for CI/CD pipelines

gh_cmd.rs imports compact_diff() from git.rs for diff formatting; markdown helpers (filter_markdown_body, filter_markdown_segment) are defined in gh_cmd.rs itself
diff_cmd.rs is a standalone ultra-condensed diff (separate from git diff)
