Build 26507729

This update fixes an issue that prevented T-junction conveyors from merging two production lines into one. In some layouts, they behaved like a 90-degree turn, leaving cargo stuck on the other incoming belt.
- Two incoming lines can now feed the selected shared output.
- The fix works with both corn and sacks.
- Direction arrows now reflect the conveyor’s routing.
- Cargo resumes moving when space becomes available downstream.
The fix was tested using a player’s affected save, where all eight queued sacks successfully reached the shared output without rearranging the conveyors.
