 * Copy the component contracts into every shipped Genome bundle.
 *
 * `docs/genome/components/*.dev.md` is the single source of truth, but a bundle
 * has to carry its own copy: `contract` is a required field on every component
 * and the path is resolved relative to the manifest, so a bundle that points
 * outside itself stops loading the moment it is installed elsewhere.
 *
 * `test/harness-rsi-genome.test.ts` fails when the copies drift, so run this
 * after editing any contract.
