Follow-up from #73597. The pegasus test suite is now largely vestigial — test_static_models.rb was already removed, and pegasus/rake/test.rake had its seed:reset dependency removed.

Remaining files to remove:

• pegasus/test/test_helper.rb
• pegasus/rake/test.rake
• Any remaining test files under pegasus/test/
• References to pegasus tests in CI config

The test:reset_dependencies task in pegasus/rake/test.rake already lost its seed:reset dependency in #73597.
