fix(libc): compute hypot with FreeBSD msun's algorithm, as titles' libc.prx does
...
hypot returned the host's hypot after an infinity check, so its last bit
and its NaN payloads depended on the host. The titles' copy is FreeBSD
msun's e_hypot.c, which sets no errno even on overflow; hypot now
computes that algorithm.

fix(libc): compute remainder and remquo with fprem1, as titles' libc.prx does
...
remainder, remainderf, remquo and remquof returned the host's functions.
The titles' copies are FreeBSD's amd64 e_remainder.S and s_remquo.S: an
x87 fprem1 loop whose remquo quotient is the sign and the three low bits
from C0, C3 and C1, and whose NaN results follow x87 NaN selection. Sony's
wrapper sets EDOM for a zero divisor or an infinite dividend when neither
argument is a NaN. All four now run that loop and set that errno.

chore(libc): synchronize nearbyint fix with main
...
Preserve the nearbyint implementation and regression coverage while incorporating current main. The write-watch registration prerequisite is now part of main.
Validation: freshly compiled production MathExact.cpp regression passes; ASan/UBSan passes with detect_leaks=0. The same fixture compiles against main Math.cpp and fails at the FE_INEXACT assertion (exit 134). Conventions, whitespace and 235 script registrations pass. Full product build and full CTest were not rerun for this synchronization.

fix(libc): compute exp with FreeBSD msun's algorithm, as titles' libc.prx does
...
exp returned the host's exp, whose last bit differs from the titles' copy on
Windows on 9,892,285 of 320 million random arguments. The titles' copy is
FreeBSD msun's e_exp.c, except that exp(1) returns the correctly rounded e,
and it sets ERANGE only in msun's overflow and underflow branches. exp now
computes that and sets ERANGE there.
