fix: use distinct critcmp group names so PR benchmark diff shows two columns

[deepjoy]

Summary

• Both the main baseline and PR benchmark results were exported under the same
  critcmp group name ("current"), causing critcmp baseline.json pr.json to
  merge them into a single column instead of producing a side-by-side comparison.
• Rename the cached baseline group to "main" and the PR export group to "pr"
  so critcmp can diff them as two distinct columns.
