Stdlib: wordwrap() — width must accept floats and numeric strings (ext/standard/string.c parity)

Problem

wordwrap() argument #2 ($width) is parsed as Z_PARAM_LONG in php-src (float truncated, numeric strings accepted). This compiler requires strict integer types and rejects valid Zend calls.

php-src reference

• php/php-src ext/standard/string.c — PHP_FUNCTION(wordwrap) / php_wordwrap

Repro (failure today)

./script/docker-exec.sh -- bash -lc 'source script/php-env.sh
php -r "echo wordwrap(\"hello\", 1.9), \"\\n\"; echo wordwrap(\"hello\", \"2\"), \"\\n\";"
php bin/vm.php -r "echo wordwrap(\"hello\", 1.9), \"\\n\"; echo wordwrap(\"hello\", \"2\"), \"\\n\";" 2>&1 || true
'

Call	Zend PHP 8.2	This compiler
wordwrap('hello', 1.9)	hello (width 1)	LogicException
wordwrap('hello', '2')	wrapped at width 2	LogicException

Scope (this repo)

• ext/standard/wordwrap.php, ext/standard/VmString.php::wordwrap()
• JIT: ext/standard/JitWordwrap.php — coerce width before __compiler_wordwrap
• test/compliance/cases/stdlib/wordwrap_width_coerce.phpt

Done when

• VM/JIT/AOT: repro matches Zend
• Invalid width ('abc', []) → TypeError/ValueError per Zend
• ./script/ci-fast.sh --filter wordwrap_width green

Merged via #8468.

Fix: wordwrap() width arg uses VmMath::parseIntBuiltinArg / JitIntdiv::lowerIntBuiltinArg (php-src ext/standard/string.c Z_PARAM_LONG) — float truncation and numeric-string widths match Zend on VM/JIT/AOT; invalid operands still TypeError.

Verification: php test/repro-maintainer/wordwrap_width_coerce.php + bin/vm.php + bin/jit.php + vendor/bin/phpunit --filter wordwrap_width — all green.
