Summary

Currently, rolldown depends on rolldown-vite for running integration tests in CI. However, rolldown’s CI always pulls the main branch of rolldown-vite. When rolldown introduces breaking changes (before a release), the tests in rolldown-vite cannot be updated immediately, causing CI failures that cannot be fixed until a release is published.

This blocks development and causes CI red status to remain unresolved.

Proposal

Introduce a dedicated branch inside rolldown-vite used specifically for testing against the latest rolldown commit. Rolldown CI should pull this branch instead of main.
