The version is stored in byte 96 of the header of the sqlite file[1].

I haven't looked but there will be some sqlite command to query it and I'm sure some viewer tools will display it as well.

You can print the version with this magical incantation:

    $ python -c 'import sys, struct; print(struct.unpack(">I", open(sys.argv[1], "rb").read()[96:100])[0])' foo.db
