feat(sbom): Add CRA Annex I compliant SBOM pipeline

Implements comprehensive Software Bill of Materials generation for
EU Cyber Resilience Act compliance with ANSSI CSPN certification path.

SBOM Pipeline:
- scripts/check-sbom-prereqs.sh: Prerequisites validation (OpenWrt, tools, Kconfig)
- scripts/sbom-generate.sh: Multi-source SBOM generation (native, feed, rootfs, firmware)
- scripts/sbom-audit-feed.sh: PKG_HASH/PKG_LICENSE feed audit with MANIFEST.md
- Makefile: SBOM targets (sbom, sbom-quick, sbom-validate, sbom-scan, sbom-audit)
- .github/workflows/sbom-release.yml: CI with CVE gating and auto-security issues

Documentation:
- SECURITY.md: CRA Art. 13 §6 compliant vulnerability disclosure policy
- docs/sbom-pipeline.md: Architecture, CRA mapping, ANSSI CSPN guidance

AI Gateway (bonus feed):
- secubox-ai-gateway: 3-tier data classification (LOCAL_ONLY/SANITIZED/CLOUD_DIRECT)
- luci-app-ai-gateway: LuCI dashboard with provider management and audit logging

Output formats: CycloneDX 1.6 (primary) + SPDX 2.3 (secondary)
Tools: syft, grype, cyclonedx-cli (auto-installed if missing)

+make sbom-quick
+
+# Validate existing SBOM
+make sbom-validate
+
+# CVE scan only
+make sbom-scan
+
+# Clean SBOM outputs
+make sbom-clean
+
+# Show help
+make sbom-help
+```
+
+### Audit Feed Packages
+
+```bash

+
+## Troubleshooting
+
+### Common Errors
+
+#### "OpenWrt version < 22.03"
+
+The native CycloneDX SBOM support requires OpenWrt 22.03 or later.
+
+**Solution:** Upgrade your OpenWrt fork or use `sbom-generate.sh` without native support
+(it will fall back to Makefile parsing).
+
+#### "package-metadata.pl not found"
+
+The SBOM generation script is missing from your OpenWrt checkout.
+
+**Solution:**
+```bash
+git checkout origin/master -- scripts/package-metadata.pl
+```
+
+#### "syft: command not found"
+
+Syft is not installed or not in PATH.
+
+**Solution:**
+```bash
+curl -sSfL https://raw.githubusercontent.com/anchore/syft/main/install.sh | sh -s -- -b ~/.local/bin
+export PATH="$HOME/.local/bin:$PATH"
+```
+
+#### "SBOM validation failed"
+
+The generated SBOM has schema errors.
+
+**Solution:**
+1. Check `sbom-warnings.txt` for missing metadata
+2. Fix Makefiles with missing PKG_HASH or PKG_LICENSE
+3. Regenerate SBOM
+
+#### "Grype database update failed"
+
+Network connectivity issue or rate limiting.
+
+**Solution:**
+- Use `--offline` mode with cached database
+- Or manually update: `grype db update`
+
+### Debug Mode
+
+```bash
+# Verbose output
+DEBUG=1 ./scripts/sbom-generate.sh
+
+# Keep intermediate files
+KEEP_TEMP=1 ./scripts/sbom-generate.sh
+```
