🛡️ Automated Security Audit — BlackShield Pipeline Scanner

Hi @kernel team 👋

We ran the open BlackShield Pipeline Scanner in an isolated, read-only, network-airgapped sandbox against kernel/kernel-images (commit 6295002) and identified 23 actionable security finding(s) (5 Critical, 18 High).

💡 You know we could do this in every PR for you, at zero cost.

BlackShield runs unified SAST, SCA/CVE reachability (VEX), Secret Detection, and IaC/Container Misconfiguration checks in a single static binary (<30s runtime) without requiring source code upload.

Overview
This PR adds .security/blackshield-audit-report.md, a BlackShield Pipeline Scanner write-up for kernel/kernel-images at commit 6295002. It catalogs 23 actionable items (5 Critical, 18 High) with file paths, rule/CVE IDs, and recommended fixes—not code or dependency changes in this diff.

The report groups issues across SCA (transitive npm deps in images/chromium-headful/client/package-lock.json), secrets (PKCS#8 key under server/e2e/test-extension-enterprise/), container IaC (multiple Dockerfiles missing non-root USER), and SAST hits in the server/API layer (zip extraction in chromium.go, fs.go, ziputil.go; path handling in process.go; vm.runInContext in browser-repl.ts; crypto/policy and exec.Command usage elsewhere). Medium/Low counts are noted in the header but only the top 23 are detailed.

The PR description also references a drop-in .github/workflows/blackshield-security.yml workflow; that file is not part of the provided diff, so reviewers should treat this change set as audit documentation unless other commits add fixes or CI.
