exec.exec() only accepts strings

Use os.availableParallelism() instead of os.cpus().length
* As https://nodejs.org/api/os.html#oscpus says: os.cpus().length should not be used to calculate the amount of parallelism available to an application. Use os.availableParallelism() for this purpose.

Thomas Breland	a96ff531da	Scale bundler install jobs with CPU count up to 8 The number of jobs should scale with the runner CPU count, up to a point. The bottleneck becomes network / disk I/O at very large numbers, and 8 seems like a reasonable maximum based on my experience at this time.	2025-10-27 12:32:05 +01:00
