Determines how the build responds to security validation failures:

• Block build on failure (block): The build will fail if ArmorCode finds security issues that violate release criteria. This is the recommended setting for enforcement.
• Mark as unstable but continue (warn): The build will be marked as unstable but allowed to proceed if security issues are found. Use this for initial integration or when you want visibility without blocking.

Note: Block mode is the default setting. When using block mode, the 'mode' parameter will not appear in the generated pipeline syntax to keep it clean.
