chore: remove dead files and duplicate workflows

- Delete build-setup.sh (empty shell script)
- Delete docker-build.sh (empty shell script)
- Delete .github/workflows/codeql.yaml (duplicate, keeping codeql.yml)
- Delete issues/ directory (3 markdown files)
- Update SECURITY_AUDIT.md to remove completed task about consolidating CodeQL workflows
- Update docs/archive/ANALYSIS_SUMMARY.md to reference codeql.yml instead of codeql.yaml
