Pull request overview

Adds an “Advanced Git Commands” section to the README to help contributors safely use common advanced Git workflows in this repo’s day-to-day development.

Changes:

• Documented git stash for managing WIP changes.
• Added examples for selectively applying/undoing commits via git cherry-pick and git revert.
• Documented history manipulation options via git reset with --soft and --hard examples.

The description for git stash pop is a bit misleading: pop applies the stash and drops it (unless it fails). Consider either changing the text to “Apply and drop the most recent stash” or using git stash apply if the intent is to re-apply while keeping the stash around.

Suggested change

	# Re-apply the most recent stash
	# Apply and drop the most recent stash
