// Integration test for CLAUDE.md §7.3 — when the deploymentId changes for
// an existing project, the next invocation must retire the old isolate
// and cold-start a fresh one against the new bundle. We assert that two
// invocations against the same projectId (but different deploymentIds)
// produce two distinct PIDs, and that each invocation returns the value
// from its own bundle (so we know the new deployment really took effect).
