02e57c81f7 mark detach as supported 
Honestly, I didn't even notice we had a compat entry for it because it
seems so trivial. But it was done as part of ATTACH.

988b16f962 Support ATTACH (read only) 
Support for attaching databases. The main difference from SQLite is that
we support an arbitrary number of attached databases, and we are not
bound to just 100ish.

We for now only support read-only databases. We open them as read-only,
but also, to keep things simple, we don't patch any of the insert
machinery to resolve foreign tables.  So if an insert is tried on an
attached database, it will just fail with a "no such table" error - this
is perfect for now.

The code in core/translate/attach.rs is written by Claude, who also
played a key part in the boilerplate for stuff like the .databases
command and extending the pragma database_list, and also aided me in
the test cases.

024d79fc0d implement write side of pragma schema_version 
It is insane that SQLite even allows this.
They actually don't if "defensive mode" is enabled:

"It is always safe to read the schema_version, but changing the
schema_version can cause problems. For this reason, attempts to change
the value of schema_version are a silent no-op when defensive mode is
enabled for a database connection.

Warning: Misuse of this pragma can result in database corruption."

We also update the compat table, which was not updated to reflect
the read version of this pragma being implemented.
