/**
 * Creates a logger preset that writes one JSON object per line to
 * `process.stdout`. Each entry includes the level label, an ISO timestamp, the
 * joined message, and the context (when non-empty). `Error` values are
 * serialized to `{ message, stack }`. Messages below the enabled threshold are
 * skipped.
 *
 * @param options - Configuration for the JSON logger
 * @param options.enabledLogLevels - Levels that should be emitted; defaults to
 *   {@link defaultEnabledLogLevels} (error, warn, success, info)
 * @returns A logger with one method per {@link LogLevel} label
 * @example
 * ```typescript
 * const logger = createJsonLogger()
 * logger.withContext({ requestId: "req-1" }).info("request handled")
 * // {"level":"info","timestamp":"...","message":"request handled","context":{"requestId":"req-1"}}
 * ```
