feat(lang): L9 resource files - registry ... from

registry NAME of RECORD [as PREFIX] from "file.lres" fills a registry from a data
file of key { field: value } entries, read at compile time with the record as its
schema: every entry is checked like a def, errors name the resource file's line,
nested records and lists of them are bare { } / [{ }] typed by their fields, and
values are expressions in the registry's module. The entries are compiled in, so
nothing parses at start-up and a build that succeeds has validated its resources.
