Apply hash-pinned generated edits for CVE-2025-14942 while keeping
wolfSSH 1.4.20 managed sources unchanged. Add the ABI header overlay,
provenance records, and real state-machine interoperability contracts.
Enable validated ECC imports and X25519 all-zero rejection through
PUBLIC build policy. Tighten wolfSSH parser bounds, overflow handling,
and signature framing with guard-page and crypto vector contracts.
