* Add Trivy Docker image security scan workflow
Scans the Docker image for CRITICAL and HIGH vulnerabilities using Trivy.
Blocks PRs on failures; runs non-blocking on main for visibility. Results
are uploaded to the GitHub Security tab via SARIF.
* Add explicit permissions to Docker security scan workflow
Set minimal permissions: contents read for checkout, security-events
write for SARIF upload to the GitHub Security tab.
