Sync

Standardize the end-of-session push. Confirm nothing is left unpushed.

Inputs

Optional: -DryRun (print actions only), -AllowMain (permit syncing on main).

Workflow

1. Confirm current branch is not main (unless -AllowMain).
2. Confirm working tree is clean. If not, warn and stop; instruct the user to commit the changes they want to keep, stash them with git stash, or discard them intentionally before rerunning sync.
3. Run git pull --rebase. If it fails, stop and report — do not force.
4. Run git push.
5. Run git status -sb and confirm branch is up to date.

Output

Short summary including the final git status -sb.
