feat(ci): add CI/CD integration — --fail-on, --compact, pipeline templates

Add threshold-based exit codes (--fail-on <severity>) and compact
output mode (--compact) to scan-orchestrator and CLI. Pipeline
templates for GitHub Actions, Azure DevOps, GitLab CI with SARIF
upload. CI/CD guide with Schrems II/NSM compliance documentation.
npm publish preparation (files whitelist, .npmignore). Policy ci
section for distributable CI defaults. Version 6.1.0.
