marker: add direction-clear, routing, and ubridge transport tests
Close the test gaps surfaced in review:

- controller (test_marker.py): direction clear vs preserve, definition-sync
  clear propagation, pinned-marker NIO routing, _markers_for_node carrying
  direction, and non-capable capture-node rejection.
- ubridge (new tests/compute/ubridge/test_hypervisor.py): unix/tcp __init__
  branches + socket-dir perms, _build_command -U/-H/debug, endpoint, stop
  socket unlink, and start() immediate-exit fail-fast.
- mcp (test_handlers.py): TestLinkMarker / TestMarkerDefinition covering
  direction tri-state (both/tx/omitted) for create and update.
