[deep-report] Resolve schema consistency criticals (timeout_minutes + labels validation)

[github-actions]

Description

Schema consistency analysis found two critical issues: (1) duplicated timeout_minutes vs timeout-minutes schema entries causing ambiguity, and (2) missing validation for labels in the compiler pipeline. Remove or hard-deprecate timeout_minutes and add label validation in validateWorkflowData().

Expected Impact

• Eliminates frontmatter ambiguity and reduces user confusion.
• Prevents invalid label values from silently passing compilation.
