Pull request overview
Backports Ruby 4.0 support work from master to the 9.0-stable branch by updating specs, dependencies, and Evergreen CI matrices for newer Ruby/JRuby and MongoDB versions.
Changes:
- Adjusted specs to account for Ruby 3.4+ Hash#inspect formatting.
- Reworked integration app tests to generate Sinatra/Rails apps on the fly and added Ruby/Rails compatibility skips/workarounds.
- Updated gem/runtime and CI compatibility metadata (gemspec, README, Evergreen config, submodules).
