Actual Behavior

The CLI prints the error but leaves the terminal hijacked by the TUI's raw mode and deadlocks the background worker threads.

	"ArtifactType": "container_image",
	"Results": [
		{
			"Target": "archlinux (archlinux 20250907.0.417472)",

			"Vulnerabilities": [
				{
					"VulnerabilityID": "CVE-TEST-1234",
					"PkgName": "filesystem",
					"InstalledVersion": "2024.01.01",
					"FixedVersion": "2099.12.31",
					"Layer": {
						"DiffID": "sha256:dummylayer"
					},
					"Severity": "HIGH"
				}
			]
		}
	]
}

2. Run a patch command

./copacetic patch \
  --image docker.io/archlinux:base-devel-20250907.0.417472 \
