fix(nextjs): Pre-warm module cache in conflictingDebugOptions test to prevent CI timeout

chargome · claude · chargome · commit 201152d519d1 · 2026-03-09T14:24:15.000+01:00
The first dynamic import after vi.resetModules() needs to compile the
entire SDK module graph from scratch, which can hang on slower CI runners.
Pre-importing the modules in beforeAll warms the V8 compilation cache.
