 Generated by `cargo xtask parity` from `xtask/data/fusion-catalog.tsv` (the toolbar commands of Fusion's Design workspace, ids and names only) and the live command registry (`solvecraft-cli commands`). A command counts as live when SolidCraft registers the same command id. This measures breadth, not depth; see ROADMAP.md and docs/oracle.md for depth.
