RAILS FIXES TEST PARALLELIZATION LEAK, BOOTSNAP PATCHES CONFIG HIJACK

Rails killed a hidden DRb thread that was preventing parallel test suites from exiting cleanly, while Bootsnap shipped an emergency fix for a config file that gets loaded by unrelated processes like Homebrew.

The parallel test infrastructure had a nasty leak: when you ran tests with `parallelize`, the parent process started a DRb service but never shut it down [1]. The accept-loop thread stayed alive after workers exited, blocking test process termination in some environments. That's fixed now [2]. In the same vein, PostgreSQL test connections were piling up in the nightly suite, hitting "too many clients" errors, so Rails also tightened connection cleanup for test-local adapters [3]. On the documentation front, Rails updated all the architecture diagrams for dark mode readability and added EPUB fallbacks for readers that don't render SVG properly [4]. Meanwhile, Bootsnap 1.24.5 shipped a critical fix: the config loader was reading `config/bootsnap.rb` even when invoked by unrelated processes like Homebrew, which doesn't have Bundler loaded and would fail [5]. Bootsnap now only loads the config file if explicitly directed to do so [6]. The Rails guides also got SQL example corrections [7]. The community survey is live on the website [8].

Action items

→ Upgrade Bootsnap to 1.24.5 immediately if running parallel processes or Homebrew in Rails project directories rails/bootsnap [immediate]
→ Pull latest Rails main to fix parallel test worker shutdown if you're hitting exit hangs rails/rails [plan]
→ Review dark mode display of your generated Rails app documentation rails/rails [monitor]
