Background

RubyGems shipped a cooldown feature (Bundler 4.0.13+) that refuses to resolve a gem version until it's been public for at least N days. That window gives the community time to vet new releases and blunts supply-chain attacks that rely on a freshly published malicious version getting pulled in immediately.

Summary

Adds cooldown: 7 to the rubygems.org source in the Gemfile, so new gem versions must be public for at least 7 days before Bundler resolves to them.

This repo has no committed Gemfile.lock, so there's no BUNDLED WITH to bump here (unlike the sibling app PRs). The cooldown takes effect whenever this Gemfile is resolved with Bundler 4.0.13+.
