Circular/Rows layout toggle in the pipeline workspace (layered
top-down DAG as an alternative to the radial view). Added the C
Protocol (Code, Claim, Consensus, Cost, Connectivity, each 0-1, Code
gates the tier below 0.3) as the candidate-repo scoring model,
seeded with real GitHub data for the Avatar node's six candidates.
First worked-example report (Avatar) written to docs/reports/.
