fix: resolve jq escape errors in OpenCode AI PR review workflow

The previous fix had issues with backtick escaping in jq strings.
Replaced inline jq string construction with printf for building the
prompt, then pass the complete prompt to jq using --arg.

This avoids escape character issues with backticks and newlines
in the JSON construction.
