fix: use jq for completion name extraction to avoid nested matches

The regex "name":\s*"..." on JSON matched nested server names inside
project objects, mixing resource types in completions. Switch to
jq -r '.[].name' for proper top-level extraction. Add jq as RPM
dependency. Add pr.sh for PR creation via Gitea API.
