feature-matrix-parity

Update the OpenClaw and Hermes comparison columns of the ZeroClaw feature-and-support matrix. Use this skill when the user wants to refresh, fill, or verify parity data in docs/book/feature-matrix-parity.toml, add a new comparison row or section to the feature matrix, or re-walk the competitor repos for support status. Trigger on: 'update the feature matrix', 'refresh parity', 'fill the parity TOML', 'walk OpenClaw and Hermes', 'the matrix shows Unknown', 're-verify the comparison columns', 'add a row to the feature matrix'.
