Forgot a point in the loom: The changes to the functions are such that it can still be called exactly as before without changes.

Note on size: The core of the line count that requires analysis is in concept.sql (81l). This is then duplicated in the migration, propagated to dbTypes. The new types propagate on inputTypes.
addConcept.feature is shuffled to exercise the new code, but it's mostly block moves.
The documentation was made into a compilable ts file; more reorg than changes.
Then small changes to use common types in roam sync and fix discrepancies.
