Wait for the initial missing-file poll before writing watched files. Otherwise uv_fs_poll can observe the created file as its baseline and never emit the expected change event. Signed-off-by: Kamat, Trivikram <16024985+trivikr@users.noreply.github.com> Assisted-by: openai:gpt-5.5

async-hooks/test-statwatcherto wait untilfs.watchFile()has observed the initial missing-file state before writing the watched files.
Without that ordering,
uv_fs_pollcan race with the test write and use thenewly created file as its initial baseline. In that case no later change is
emitted, so the test can hang until the harness timeout.
