@sidequest/core is the core package of SideQuest, a distributed background job queue for Node.js and TypeScript applications.

/**
 * Generate serializable errors.
 * Error objects are not fully serializable by default because their fields are not enumerable.
 * For example:
 *   const err = new Error("my error");
 *   const foo = { ...err };        // foo is {}
 *   JSON.stringify(err);           // returns '{}'
 * This function extracts all own properties, making the error serializable for logs and transport.
 * @param err The error object to serialize.
 * @returns A serializable error data object.
