 * Thrown when a registered workflow or activity schema cannot be converted

 * server-side observability (logs and telemetry) and non-HTTP callers
 * (the in-process MCP builder, programmatic users of `buildRegistrySnapshot`)
 * can identify which registration is broken. The HTTP REST binding
 * deliberately masks this on the wire as a generic `500 / Internal server
 * error` so a misbehaving registration cannot leak schema layout to clients
 * that only have `system:read`.
