* feat(wsl-mover): pause a moving project's terminals through Sleep and prove they exited (D1b-5d)

* fix(wsl-mover): gate again under the fence, swap journal phases atomically, keep sessions frozen through commit (D1b-5d)

* test(wsl-mover): the fence e2e walks the journal one phase at a time, as a move writes it (D1b-5d)
