The UI half of D-106 (D-6 parity with `clide env path`): an ordered
preset editor — add/remove/reorder, a missing-dir warning, a worktree
note naming the shared main repo, and capture-from-login-shell
suggestions adopted with one click. Writes land on the same user-scope
key the CLI verbs use and publish on the same channel, so both
surfaces stay live off the store notifier.
