Umut CANandClaude Opus 5.5 7bfba02ef0 fix(task-5): fittings bridge every port pair, reducers found however the pipe meets them, unread-layer lines keep their labels
- A three- or four-way fitting joined its ports as a star around the port
  seen first, so the diameter carried into an unlabelled branch depended on
  record order. Every port pair is now bridged; two sizes equally near stay
  unassigned whatever the order (six-order parametrised test).
- A reducer was seen only through free ends in its box. It is now also found
  where pieces meet at a vertex inside its box (a line broken at the
  reducer) and where a straight segment is drawn through the middle of its
  box (cut at the foot of the box centre). A direct label holds for its
  entity only on its side of every reducer.
- A diameter or direction label nearer to an open line on a layer that is
  not read belongs to that line: it is dropped and listed in
  stats.labels_skipped instead of landing on the nearest read pipe.

Headless engine only: no new ActiveX call, so no live probe applies.
