Module selection 

Shared vocabulary for saying which files a command should work on.

Two selections exist, deliberately as separate types:

• RowSelection for commands that query rows (search, embed, faces, classify, locations). It can filter on anything recorded.
• PathSelection for commands that walk a filesystem (scan, watch). It can only filter on what is knowable before a file is read.

Keeping them separate is the point: adding a predicate to the row side cannot change what scan accepts, because scan does not take that type.

This module holds the primitives both share. The selections themselves and their resolution follow in the same module.
