Details
The metadata cache directory (defaults$cache_dir) is resolved from the
ISTATLAB_CACHE_DIR environment variable
(Sys.getenv("ISTATLAB_CACHE_DIR", unset = "meta")). Set this variable,
for example in .Renviron, to share a single metadata cache across
multiple projects; when unset, the local "meta" directory is used.
