Confirm hook appending comment already addresses review feedback

[Copilot]

The review feedback on PR #127 requested adding a comment to indicate that appended hook code is an extension of the existing script rather than a standalone section. This has already been addressed in commit 7eca2be.

Implementation

Line 162 of cmd/initialize/main.go prepends a comment before the hook body:

updated += "\n# git-drs pre-push hook\n" + hookBody

When an existing pre-push hook is detected, the resulting file structure is:

#!/bin/sh
# [existing hook content]

# git-drs pre-push hook
remote="$1"
if [ -n "$remote" ]; then
  git drs prepush "$remote"
else
  git drs prepush
fi

The comment clearly delineates the git-drs extension from any existing hook logic.
