refactor(cj-cache): rename to cj-cache-lib for naming consistency

Library files in this codebase are suffixed `-lib' (system-lib.el is
the established precedent).  The Phase 5 cache helper landed as
cj-cache.el; the spec's table proposed names without the suffix and
I followed it without checking against convention.  Fix the
inconsistency now while there are only two consumers and one test.

Rename modules/cj-cache.el -> modules/cj-cache-lib.el; update
provide form, file header, and the three (require 'cj-cache) call
sites in org-agenda-config, org-refile-config, and test-cj-cache.
No behavior change.
