walks-export: reduce worker Node heap to 128 MB for Serenity subprocess (#189, #114)

The Serenity worker subprocess was inheriting the parent server's 460 MB Node heap limit, which is excessive for a process that only orchestrates Chrome via WebdriverIO. This left less headroom for Chrome itself within the VM's memory budget. Set NODE_OPTIONS=--max_old_space_size=128 explicitly on the spawned process, freeing ~330 MB for the Chrome session. Stopgap until #114 moves the worker to a dedicated process.
