Release blocker: helper-runtime prelink STALE after MathBaseConvertJitHelper (#26903)

Problem

./script/release-readiness.sh --json reports user_release_ready: no because:

helper-runtime-prelink: STALE ext_standard_MathBaseConvertJitHelper_php (/ext/standard/MathBaseConvertJitHelper.php)
— 361 fresh, 1 stale, 0 broken

Source drift from #26903 (Stdlib: fix AOT hexdec/bindec NestedJIT insert and string ABI) without a matching prelinked/helper-runtime/x86_64-linux refresh.

Done when

• php script/check-helper-runtime-prelink.php --strict → 0 stale
• ./script/release-readiness.sh --json → user_release_ready: yes (helper-runtime-prelink ok)
• Committed unit bytes rebuilt from current MathBaseConvertJitHelper.php (no restamp)

Refresh

./script/docker-exec.sh -- bash -lc 'PHP_COMPILER_EMIT_JOBS=1 php script/emit-helper-runtime-object.php --unit=/ext/standard/MathBaseConvertJitHelper.php --prelink'

claim: worker-lane-B — starting this run (Pillar 1 user_release_ready red; refresh MathBaseConvertJitHelper prelink)

Merged #26916 (27f8940e).

Verification:

• php script/check-helper-runtime-prelink.php --strict → 362 fresh, 0 stale, 0 broken
• ./script/release-readiness.sh --json → user_release_ready: yes (helper-runtime-prelink ok; inventory/spine/north-star5-fast/vm-driver-probe ok)

Rebuilt committed unit.o + fingerprint from current MathBaseConvertJitHelper.php (drift from #26903). No restamp.
