failure to import

[DanTulovsky]

Hi, with zen 1.19 I am not able to export the arc data, I get a bunch of failures like this:

$ /usr/bin/python3 migrate_arc_to_zen.py
...
2026-03-04 09:46:35,589 - ERROR - Failed to create pinned tab 'Mango Languages': no such table: zen_pins
2026-03-04 09:46:35,590 - ERROR - Failed to check if tab exists: no such table: zen_pins

for basically everything. Maybe the underlying format was changed?

thanks for making this, it did work in the 1.18 version just fine...
