Remove the unused React Native Markdown renderer. Pin safe YAML, shell quoting, tar, and cache dependencies; upgrade npm within the 11 series and apply upstream fixes to its hidden bundled Undici and cache copies.
Add actual-consumer security regressions and an opt-in real npm/ACP upgrade verifier. Typechecks, Web build, Android APK/signature checks, and 2,997 tests passed (23 skipped). Real old-to-new npm installs, ACP initialize, rollback, restart, and fallback retention passed under the desktop Electron runtime.
Android USB-device validation and full desktop automatic-update release gates remain pending. Dependency audit is reduced from 85 to 74 unique advisories; this is not a complete security clearance.
