Describe the new feature

sqlitebrowers is a GUI that seems to aim to replace sqlite3.

One thing that I noticed missing is the .checksum [--schema --sha3-nnn] command.
This is handy when packing up a database for archiving and/or distribution.
It's described here: https://www.sqlite.org/cli.html#sha3sum

The database integrity checks described on the same page, would also be good candidates for the "Tools" menu discussed in #1434 ...

See also the pragmas integrity_check https://www.sqlite.org/pragma.html#pragma_integrity_check, quick_check, and foreign_key_check on the same page
