A vitest pool worker is the one launch path that never received
`--liftoff-only`, so the suite compiled tree-sitter grammars on the
turboshaft tier. Once ~640 extraction tests have warmed a grammar function
up, its background tier-up job (Turboshaft LoopUnrollingPhase, symbolized
from the native stack) exhausts a compiler Zone and aborts the worker:
`Fatal process out of memory: Zone`, which vitest reports only as "Worker
exited unexpectedly" with the file's remaining tests unrun.
Pass WASM_RUNTIME_FLAGS through poolOptions.forks.execArgv, so the test
process matches the bundled launcher, the CLI re-exec and refresh-launcher.
V8 flags are process-global, so parse worker threads are covered too.
Linux x64, Node 24.15, `__tests__/extraction.test.ts` (655 tests):
without the flag 3 of 4 runs died at the same test (639 passed);
with it 2 of 2 passed, in 19–24s instead of 34–41s. Neither
`--no-wasm-loop-unrolling` nor `--no-wasm-dynamic-tiering` prevents it.
