patch

Improve workflow-step scope gating for pre-merge checks. The built-in Frontend UX Design workflow step now auto-skips using both diff scope and declared ## File Scope signals, reducing off-domain runs. Prompt-mode pre-merge workflow steps now perform end-of-step file-scope enforcement with a new workflowStepScopeEnforcement project setting (block default, warn, off) and honor task scopeOverride bypasses.
