Every scenario from the contract, against a real daemon, tmux and git: collision suffixes with both trees working, foreign directories sidestepped without adoption, the guarded kill and its refusal breakdown, save-then-kill succeeding, --force retaining the tree, natural exits settling dirty and pristine worktrees differently, the retained list with reasons, reclaim keeping the branch, and the store surviving a daemon restart. Worktree specs are built through their wire shape so the tests carry no reference to WorktreeSpec.cleanup_on_kill, which #87 is removing.
