RStudio 2025.05 supports ulimit -m; set it

[HenrikBengtsson]

The latest RStudio 2025.05 respects ulimit -m settings. From the NEWS:

• Added memory limit monitoring to RStudio (Linux only for now). If ulimit -m is set, this limit is displayed in the Memory Usage Report. As the limit is approached, a warning is displayed, then an error when the limit is reached. When the system is low on memory, the session can abort itself by shutting down in a controlled way with a dialog to the user. See the new "allow-over-limit-sessions option in rsession.conf. (rstudio-pro#5019).

I've confirmed that there is at least a warning displayed at the bottom of the GUI when approaching or going over the limit.
