Implements ProjectResolution with TDD: fetches a [width, height] pair from a resolution series by loop index, clamping out-of-bounds indices to the last entry and returning (512, 512) defaults on error or missing key. Also registers the node in mappings and updates TestNodeMappings count to 4. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
