Walkthrough

The change migrates Director, Health Monitor, and NATS packaging and jobs from Ruby 3.4 to Ruby 4.0. Gem specifications now require Ruby 3.4.0 or newer. Blobstore client unit tests update identifier fixtures and related command expectations, method calls, and error messages. The CI vendored-package check also tracks the Ruby 4.0 package.

• Update gemspec minimum Ruby requirement to >= 3.4.0.
