test: ./check mount now also exercises the daemon-backed --socket FUSE path
The mount stage previously only tested the in-memory --seed mount, so the daemon-backed write path (DaemonBackend) was never regression-guarded -- which is exactly how a VM shipping an old cube-server (lacking the raw* commands) shipped undetected. The mount stage now runs the full regression suite against BOTH a --seed mount and a --socket mount (with its own fresh daemon), and adds a durability-across-restart assertion proving the FUSE view is a real durable store. run_fs_tests is now backend-agnostic (self-seeds its fixture).
