CLI generators not so random

When running generators from the new CLI feature, they are not very random. Here is the output of calling "chance word" several times in a row:

vapik
teogefe
suvaflud
ut
gibgewuga
cim
gendadel
ate
rizjefjo
ro
cim
cof
cim
mi
gibgewuga
gibgewuga
gendadel
ut
teogefe
alogikfur

You can see "gibgewuga" is repeated 3 times, as is "cim". "gendadel" and "teogefe" are repeated twice.

It looks like this is not specific to "word", but rather systemic. Similar results occur with "chance name":

I haven't investigated yet, but I assume this is related to not having a true source of entropy at startup. For the CLI to be useful, I think it needs a better source of entropy. I'm sure even the CPU tick time would give better results.

Start by running the CLI commands shown in the report, `chance word` and `chance name`, and trace the generator randomness initialization at startup. Investigate why repeated calls produce duplicate values; done means the CLI uses a stronger startup entropy source and the reported systemic repetition is no longer reproducible.
