Returns the DuckDB connection that all ducklake functions share. The first
call creates the connection automatically, so you never need to set one up
yourself. If you want ducklake to use a connection you have created (for
example, one shared with other tools), register it first with
set_ducklake_connection().
Details
The automatically created connection is backed by a temporary database file
(not :memory:) with a spill directory configured, so larger-than-memory
operations work out of the box. It is closed automatically when the R
session ends.
