test(mutation): repoint the indirect-ownership pin at a chain that still exists

#2499 took `scroll-edge-state` out of the interaction runtime's imports, which left
the indirect-ownership example naming a test that no longer reaches that kernel, and the model gate
only noticed when a recording change made it runnable again. `back-runtime.test.ts` reaches edge
detection through the daemon without importing the kernel file, so the omission this assertion exists
to catch is still asserted.
