[BUG] thinning_wall anchors are oriented incorrectly

[hansmi]

Describe the bug

The thinning_wall module produces incorrectly oriented anchors. They're rotated by 90° on the Z axis, making attachments difficult.

Code To Reproduce Bug

include <BOSL2/std.scad>
include <BOSL2/walls.scad>

thinning_wall(h=14, l=200, thick=22, strut=1, wall=20)
show_anchors();

Expected behavior

The anchors are supposed to match the generated wall.

This test should be done with actual dev version of 2026 and not with 5 year old release.
BOSL 2 is developed for new release coming next in 2026.

In Readme or About it should be here in text that a 2026-dev-version should be used.
