Thank you for your contribution! Sashiko AI review found 1 potential issue(s) to consider:
- [Medium] The INT and TERM signal trap removes the temporary file but fails to exit the script, causing the script to resume execution and proceed with an empty or partial package list after an interrupt.

perf build: install-build-deps: add RHEL family devel package mapping

This patch extends the Fedora package mapping in install-build-deps.sh to the
RHEL family (RHEL, CentOS Stream, Rocky Linux, AlmaLinux, Oracle Linux). It
adds logic to check enabled repositories via dnf repoquery to handle packages
that are missing or located in optional repositories like CRB or EPEL.

[Severity: Medium]
Will this script continue execution if the user sends SIGINT?

Since the trap removes the temporary file but doesn't explicitly exit, an
interrupt during package_set() would delete the file and then resume execution.
The cat command would fail because the file is gone, and the script might
continue on to the sudo installation phase with an incomplete package list.

Should the trap call exit for INT and TERM signals?
