No migration on this as it has no practical impact, just a slight
cleanup for new installations.
Also a refactor of how we declare single column primary keys, for
consistency.

This changes the database structure to use one database per folder, with
a small main database to coordinate. Reverts the prior change to buffer
all files in memory when pulling, meaning there is now a phase where the
WAL file will grow significantly, at least for initial sync of folders
with many directories.
