/**
 * Phase 1 (ADR-1244 / issue #1430): versioned capability manifest.
 *
 * The build-time validator in scripts/gen-capability-registry.cjs must:
 *   - REQUIRE a semver `version` on every capability (the registry rejects a
 *     manifest without one — ADR-1244 D1).
 *   - Shape-validate the optional ecosystem envelope fields `engines`,
 *     `compatVersions`, `integrity`, `provenance` when present.
 *
 * Every native capabilities/<id>/capability.json must carry a valid `version`
 * and `engines.msd` (the conformance / parity requirement: the build fails when
 * a native manifest lacks a version).
 *
 * These are behavioral tests against the exported validator + generator
 * pipeline — no source-grep. They mirror the harness in
 * tests/capability-registry.test.cjs (makeTempCapDir + loadAndValidate +
 * buildRegistry).
