Kristian MyramandClaude Haiku 5.5 be99fecfdc #1010: recover a static Orientation's Y angle without losing precision near gimbal lock ...

uniform_parent_pose took the Y angle from asin, which loses precision within about 1e-6 degrees of
+-90. The Y angle now comes from atan2 on cos(Y), as the X and Z angles already do. The gimbal
branch and the principal-range output are unchanged.

A new test parents a static Orientation with Y 1e-6 degrees off gimbal lock under a uniform
parent. Its largest corner displacement was 3.3e-8 px before this change and 1.5e-14 px after.
