          Automated weekly update of pattern adherence tracking data.

          ### What Changed
          - Pattern-to-forms mapping updated
          - Compliance percentages recalculated
          - Forms × Patterns matrix regenerated

          ### Files Updated
          - \`src/assets/data/metrics/pattern-adherence.json\`
