feat(editor): the branch of a switch leads into the free end of a track: when the angles match the switch slides so its branch lies on the track's line, otherwise an arc of the switch radius right after the switch turns into it (with a straight between for a parallel track); works while placing a switch (drag toward the end) and when dragging from the branch end of a placed one, the track is shortened when it reaches past the branch; self-test switchlink / branchlink
