Describe the bug

Some warnings are getting printed to stdout instead of stderr:

$ dthk query "[:find ?e . :in $ :where [?e :bad/attr]]" db:dthk.edn 2>/dev/null
2024-09-19T07:18:41.583Z toast WARN [datahike.db:?] - Attribute :bad/attr has not been found in database
60
$ dthk query "[:find ?e . :in $ :where [?e :bad/attr]]" db:dthk.edn >/dev/null
$

What is the expected behaviour?

I expect all warnings/errors to print to stderr, so I can reliably parse results as EDN (and check for warnings separately).

$ dthk query "[:find ?e . :in $ :where [?e :bad/attr]]" db:dthk.edn 2>/dev/null
60
$ dthk query "[:find ?e . :in $ :where [?e :bad/attr]]" db:dthk.edn >/dev/null
2024-09-19T07:18:41.583Z toast WARN [datahike.db:?] - Attribute :bad/attr has not been found in database

How can the behaviour be reproduced?

Run the above command with latest CLI :)
