@hulumi/drift: Orphan reconciler accepted externally supplied execute plans
Impact: @hulumi/drift versions before 1.3.2 could accept externally supplied execute plans without sufficient provenance checks, allowing unsafe reconciliation input to be treated as trusted.
Patched in 1.3.2: execute-plan handling now validates provenance and rejects untrusted plans, with regression coverage.
Remediation: upgrade @hulumi/drift to 1.3.2 or later.
