arnav-hiwarkarandClaude Opus 5.5 a76bbf05f7 Effects: re-pin the macOS golden hashes #2944 changed by rounding ...

#2944 (497a056c) normalises each box-blur mean in f64 and rounds once
(it was rounded to f32 first, then scaled), and counts repeated edge pixels
with one multiply instead of adding them one by one. Its PR states results
change only by float rounding, and it added the focused regression test the
golden-test rule asks for (box_row matches a direct sum). The golden hashes
are only enforced on aarch64 macOS, so Linux PR CI passed, and every
completed macOS CI run on main since #2944 has failed (497a056c's own run
was cancelled by a newer push).

Bisected on an M5: the golden tests pass at ed085bd4 and fail at 497a056c
with the same 52 hashes macOS CI reports. All 52 are 32 bpc frames of
effects that blur through box_plane/gauss_plane (Lightning, Advanced
Lightning, Inner/Outer Key, Caustics, Paint Bucket, Vegas); every 8 bpc frame
is unchanged. All 52 frames differ by at most 4.8e-6 per channel, with no new
non-finite values.

Only the pinned hash values change; LIBM_VARIANTS is untouched.
