Test hangs to timeout instead of failing fast if dev server exits between rebuilds

nit: The stderr reader only rejects whatever `waiter` is live when the stream closes (line 71); a `waiter` created afterward is never settled. If the server crashes while `waiter === undefined` (e.g. during `liveBlocks()` or right after a resolve), the next `rebuild()` sets a fresh waiter, `Bun.write` succeeds against the temp dir, and `await promise` hangs to the 60s timeout with no stderr dump. Latch the exit error and check it in `rebuild()` (or race `promise` against `stderrClosed`) so the f
