Tasks 3.3 and 4.1. - vfc curl and openssl-cve-2021-3449 excerpts re-harvested through the shared library: whole functions with upstream_start headers, the vendored key redacted code-safely, no truncated bodies. - vfc/recipes.toml carries mode, fix_path and function anchors; training/manifest.jsonl regenerated. - Juliet CWE-121 strcpy pair gets its buffer declarations back so the vulnerable side is a real overflow again.
