wip: Make cross-module visibility explicit via Visibles structs

All access is/will be through interfaces accessed through these structs.

This introduces several distinct storage units:
+ DB for server state
+ DB for codeql databases
+ query pack store

The steps for manually creating needed databases are in the README
