Backport #2351: [vitest] Fix local imports failing to load in test step bundles

[github-actions]

Automated backport of #2351 to stable (backport job run).

AI recommendation: This is a bug fix for the vitest builder externalizing project-local step imports, and the PR body explicitly states the stable channel is affected (the .ts→.js rewrite, present on stable via rewriteTsExtensions: true, makes every externalized local import fail). The fix relies on the bundleTransitiveLocalStepDependencies option, which already exists on stable (in packages/builders and packages/nitro), so it does not depend on main-only behavior; the only difference is that stable uses the older createWorkflowsBundle/createStepsBundle API, which is a conflict-resolution concern rather than a reason against backporting.

Merge conflicts were resolved by AI (opencode with anthropic/claude-opus-4.8). Please review the conflict resolution carefully before merging.
