Poem

I twitch my whiskers at Ruby’s new sheen,
From 2.7 burrow to 3.4 fields green.
The cache napbed left folded away,
Builds hop along in a brisker sway.
Thump-thump—CI sings a brighter day! 🥕

18-20: Restore bundle cache with a Ruby-versioned key

By commenting out the restore_cache step we're losing all benefit from the bundle cache. Instead of disabling it, update the cache key to include the new Ruby major version so we avoid mixing 2.7 artifacts while still getting cache hits.

-#        # Restore bundle cache
-#       - restore_cache:
-#           key: bundle-{{ checksum "Gemfile.lock" }}
+       # Restore bundle cache
+       - restore_cache:
+           key: bundle-ruby-3.4-{{ checksum "Gemfile.lock" }}

And adjust the save_cache block on Line 30 to use the same bundle-ruby-3.4-{{ checksum "Gemfile.lock" }} key.
