fix(hatch): wrong-way giant boundary arcs in blocks — bump acadrust

Hatches inside blocks (xref_Plan-Sade) drew some boundary arcs as their
near-full-circle complement, covering huge areas — in the pattern clip
when rendered through the INSERT, and in both pattern and boundary wires
after EXPLODE.

Root cause (acadrust 64efaf8): the stored sweep of a boundary arc is
always forward and AutoCAD encodes a wrap through 0 by writing the end
angle ABOVE 2π (5.81 → 6.64 for a 0.83 rad arc). transform_hatch
normalized angles into [0, 2π), turning such arcs into their 5.46 rad
complement on ANY insert pass-through — even a pure translation, which
is why the same hatch looked fine outside the block. The fix transforms
only the start angle and carries the stored sweep over unchanged
(invariant under rotation and mirror); RAW vs exploded edge angles are
now bit-identical on the reporting file.
