Trust: refresh 27 stale DOM/helper-runtime prelink units (#32122)

[PurHur]

Summary

• Refreshed 27 stale committed helper-runtime units (mostly ext/dom/* from AOT: DOMXPath //@* NodeList::item(N>0) host-fold materialization (#32003) #35706–AOT DOM: adoptNode cross-document reparent via LiveSlots detach (#19654) #35726) via targeted --unit= emit + publish-helper-units-prelink.php — no full corpus sweep.
• Restores check-helper-runtime-prelink --strict to 441 fresh / 0 stale / 0 broken, keeping cold-build on the fast committed-cache path (Release blocker: committed helper-runtime cache is stale, so a clean checkout cannot compile hello world in 2 minutes #24302 / Release v1.1.0: fix cold-build-check compile_failed on hello world (LLVM Module.php line 180; re-#24302) #32122 follow-up to Trust: refresh stale helper-runtime prelink (restore user_release_ready) #34701).

Root cause

DOM AOT helper sources changed in recent merges; committed prelinked/helper-runtime/x86_64-linux/units/* fingerprints drifted. Cold builds still worked (local re-emit) but violated strict prelink freshness and risked compile timeouts on clean checkout.

Verification

./script/aot-smoke.sh
→ aot-smoke: 8 passed, 0 failed

./script/docker-exec.sh -- bash -lc './script/cold-build-check.sh'
→ cold-build-check: ok — clean-checkout compile of hello world took 8s (budget 120s)

./script/docker-exec.sh -- bash -lc 'php script/check-helper-runtime-prelink.php --strict'
→ check-helper-runtime-prelink: x86_64-linux — 441 fresh, 0 stale, 0 broken

Not run: ./script/release-readiness.sh --json (Compile Tester lane), full ci-local.sh, differential sweep.

Closes #32122 (trust follow-up — prelink freshness debt).
