Checklist

• Have you checked and followed all the points mention in the CONTRIBUTING.MD
• Have you validated script on UBI 9 container
• Did you run the script(s) on fresh container with set -e option enabled and observe success ?
• Did you have Legal approvals for patch files ?

Notes:

• Tested on UBI 10.0 only (not UBI 9) — Tested on: UBI:10.0 reflects this
• No patch files in this PR; ppc64le changes are in the source branch (afsanjar/openrag@ppc64le-0.5.1)
• python3.13 is not available in UBI 10 dnf repos; script uses uv python install 3.13 instead
• Build log from fresh UBI 10 container on ppc64le (Power10):
