Root cause: switch-traffic.sh was modifying Traefik config in the CI checkout
directory ($GITHUB_WORKSPACE) instead of the deployment directory ($DEPLOY_PATH).
Traefik never saw the weight changes, so traffic stayed on old containers.
Changes:
- Add DEPLOY_PATH environment variable support to all CI scripts
- Add --force-recreate flag to ensure containers are recreated with new images
- Add image verification step to confirm containers use expected images
- Add weight verification to confirm Traefik routing was updated
- Add routing validation step to verify traffic switch succeeded
