test(vm): replace network-dependent happy-dom #16277 repro with deterministic tail-call repro - #36823

Test 3's design is inverted: `ErrorInstance::finalizeUnconditionally` runs via `Heap::finalizeMarkedUnconditionalFinalizers`, which iterates `forEachMarkedCell` — it fires only on errors that **survive** the collection, not on ones that are dropped. Since all 64 errors here are unreachable at `Bun.gc(true)`, they're simply swept without materializing `.stack`, so the loop + GC can be deleted without changing the outcome and the test reduces to a repeat of test 1's eager-`.stack` path. To actuall

Since this file guards a segfault, consider running at least test 3 (the pure "does not crash during GC finalizer" check) via `Bun.spawn([bunExe(), "-e", ...])` and asserting `exitCode === 0` / `signalCode === null`. As written, a regression of #16277 segfaults the test-runner process itself at address 0x5, taking every subsequent test in the shard with it rather than reporting one clean failure. A single spawn under debug+ASAN is still ~10× faster than the 16.5s baseline this replaces, so it do

The error-message assertions in test 1 and test 2 disagree: line 41 hedges with `|| stack.includes("not callable")` while line 61 in the vm-context test asserts strictly `toContain("is not a function")`. Your own verification table shows test 2 passes on every configuration (1.1.42/1.1.44/debug+ASAN/`useJIT=0`), which proves the strict form works everywhere — so the `"not callable"` branch on line 41 is dead weight that weakens the assertion. Drop the OR and use `expect(stack).toContain("is not
