php-in-php: delete GzStreamIoJit — route gzopen/gzread JIT through GzStreamJitHelper PHP (#1492)

Problem

lib/JIT/Builtin/GzStreamIoJit.php (~882 LOC) lowers __compiler_gzopen / __compiler_gzwrite / __compiler_gzread / … with inline libz LLVM on the shared stream handle table. VM paths already use ext/standard/VmGzStream.php (pure PHP via VmGzStreamPure + VmZlib, #8936).

php-src reference

• php/php-src ext/zlib/zlib.c — gzopen/gzwrite/gzread/gzclose

Repro

wc -l lib/JIT/Builtin/GzStreamIoJit.php
./script/docker-exec.sh -- bash -lc 'source script/php-env.sh
php bin/vm.php -r "\$p=sys_get_temp_dir().\"/gz_\".getmypid().\".gz\"; \$h=gzopen(\$p,\"w9\"); gzwrite(\$h,\"hi\"); gzclose(\$h); var_export(gzfile(\$p)); @unlink(\$p);"
'

Done when

• JIT embed + standalone AOT route through GzStreamJitHelper PHP; GzStreamIoJit.php deleted
• Shrink test + gz* compliance green
• Spine includes helper + runtime bridge

claim: PHP Runtime → PHP — batch (issues #13420)

[PurHur]

Merged via #13421 — deleted GzStreamIoJit (~882 LOC); JIT/AOT gz* routes through GzStreamJitHelper → VmGzStream. Verified: GzStreamIoRuntimeShrinkTest, VM gzfile repro, bootstrap VM driver probe, spine sync.
