Adds
atom memory-safety, which runs chen's C/C++ memory-safety overlay and writes the findings as JSON.--memory-api-configdescribes project allocator and copy APIs;--min-confidencefilters findings.--suggest-defines/--auto-defines: a census of the#ifblocks hidden by undefined build macros, which suggests defines or applies the ones it can prove.Results on the memory-safety corpus (baseline 0%): recall 62.77% / precision 98.33% at medium confidence, 75.53% / 95.95% at low, no findings on the negative controls. FFmpeg libavformat CVE litmus: 5/13 at medium and 7/13 at low (6 and 8 with
--auto-defines), with no findings at the fixed sites.Needs chen 4.0.0 (AppThreat/chen#188). Until it is published, CI builds chen from main in a temporary step (
.github/actions/chen-from-main), so the checks pass once the chen PR is merged. Remove that step after the chen release.
