Missing guidance to exit Copilot CLI in bug fix workflow

[jBarrineau]

In 03-development-workflows/README.md, the 'Putting it all Together: Bug Fix Workflow' section includes a code block with the command:

...

# 3. Generate tests for the fix
> @samples/book-app-project/books.py Generate pytest tests specifically for:
> - Full author name match
> - Partial author name match
> - Case-insensitive matching
> - Author name not found

# 4. Generate commit message
copilot -p "Generate commit message for: $(git diff --staged)"

# Output: "fix(books): support partial author name search"

Issue: The documentation doesn't guide users to exit the GitHub Copilot CLI before executing this command. This can confuse users who are running interactive sessions.

Suggested fix: Add a note or step instructing users to exit the Copilot CLI first before running the command. OR demonstrate how you can generate a commit message from within the current session.
