Cleanup

Remove what shipping left behind. Nothing else.

Read shared/git.md first — in particular that a rebase or squash merge rewrites commits, so git branch --merged does not list a branch that landed. Every deletion here is verified against the forge, never against git alone.

git worktree list
git status --porcelain

Print one table. Nothing is removed until it is printed:
