Announce the cooldown feature shipping in Bundler 4.0.13. Cooldown holds back gem versions until they have been published for at least N days, giving freshly-pushed releases time to be vetted before resolution picks them up. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Link the cooldown announcement from the 4.0.13 release notes, and point the cooldown post's upgrade step back at the release announcement. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Link the v2 compact index effort that exposes per-version created_at, and thank the rubygems.org team whose server-side groundwork cooldown sits on. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

Changes:
- Add a new post explaining the cooldown feature, how it works, and how to enable/configure it.
- Update the Bundler 4.0.13 release post to link to the new cooldown announcement post.
