fix: instruction telemetry requires many file descriptors on high core-count systems

[harp-intel]

This pull request improves the robustness of the instruction telemetry script by ensuring that the system's open file descriptor limit is high enough to support monitoring on large systems. The main change is the addition of logic to check and, if possible, increase the soft open-file limit before running telemetry. This prevents failures due to "Too many open files" errors when monitoring many CPUs.

Resource limit handling:

• Added logic to calculate the required open file descriptor limit based on the number of CPUs, ensure the current limit is sufficient, and attempt to raise it if needed. If the limit cannot be raised, the script now exits with an informative error message. (internal/script/scripts.go) [1] [2]
