Bootstrap: sync spine for ReflectionEnumFromName (#16909)

[PurHur]

Summary

• Add require_once entries for three inventory files missing from compiler_lib_spine_smoke after Stdlib: ReflectionEnum::fromName() static factory missing (PHP 8.2+, ext/reflection/php_reflection.c) #16877: lib/VM/Builtin/ReflectionEnumFromName.php, ext/dom/ElementInsertAdjacentElement.php, and ext/standard/VmNullNumberParamDeprecation.php
• Restores spine coverage sync and release-readiness quick gates (5/5 green)

Closes #16909

Root cause

PR #16901 added ReflectionEnumFromName.php for ReflectionEnum::fromName() on PHP 8.2+ profile without updating the self-host spine bundle. Inventory auto-regeneration also surfaced two additional uncovered units.

Verification

php script/check-selfhost-spine-coverage-sync.php
# check-selfhost-spine-coverage-sync: OK (spine covers all 4172 inventory files, 1 deferred (#1960, #1922))

./script/docker-exec.sh -- bash -lc './script/release-readiness.sh --json'
# user_release_ready: yes — 5/5 quick gates green:
#   bootstrap-inventory --check: OK 4172/4172
#   spine-coverage: OK
#   root-readme-sync: OK
#   north-star5-verify --fast: OK
#   bootstrap-selfhost-vm-driver-execute-probe: OK
