Rails 8 support

Add Rails 8 Compatibility

What does this do?

Rails 8.0 support, allowing host applications using Rails 8 to use this gem without version conflicts.

How does it solve it?

• Updated ActiveRecord dependency: Changed from "< 8" to "< 9.0" in gemspec
• Added Rails 8 testing: Created Gemfile.rails-8.0-stable and updated CI matrix
• Version bump: Updated to 3.4.0
• Improved Rakefile: Better database setup handling for development

• Code modernization: Added frozen string literals and Ruby 3.0+ requirement

Testing?

• ✅ All 41 tests pass on Rails 8.0 with Ruby 3.2+
• ✅ Verified compatibility across Rails 6.1, 7.0, 7.2, and 8.0
• ✅ No breaking changes in Rails 8's ActiveRecord internals affect this gem
• ✅ CI now tests all supported Rails/Ruby combinations

should we be removing Rails 6.0 support?

[wendy-clio]

Agree, since it's not officially supported anymore and most of our app has moved on.

[wendy-clio]

It will be great to take the chance to remove the 6.x version support. The upgrade itself LG!

Bug: Ruby 3.0 Excluded Despite Rails Compatibility

The CI matrix includes Ruby 3.0 but then excludes it from all Rails versions (7.0, 7.2, 8.0), leading to zero test jobs for Ruby 3.0. This is incorrect because Rails 7.0 officially supports Ruby 3.0, and the blanket exclusion contradicts the gemspec's required_ruby_version = '>= 3.0'.

LGTM

Took a look, mostly for CI changes as this is one of our few public repos so I wanted to make sure we didn't introduce any triggers like pull_request_target that can add security risks.
