Support the 0x collect-delay arg

[stephenh]

Afaiu clinic flame runs on top of 0x, which has a --collect-delay parameter that seems very useful to ignore "initial boot" noise:

davidmarkclements/0x#239

It would be great to be able to set this when running clinic flame.

There is undocummented delay env variable but sadly it does not work, issue is reported here #416, source code of the feature here https://github.com/search?q=org%3Aclinicjs+NODE_CLINIC_DOCTOR_TIMEOUT_DELAY&type=code 🥺
