Directory for decompressed, hash-keyed caches. Honours $FLOWR_SIGDB_CACHE / $FLOWR_CACHE_DIR, then the
platform cache home ($XDG_CACHE_HOME on Linux, %LOCALAPPDATA% on Windows), then ~/.cache/flowr, falling
back to the OS temp dir (so it works in a read-only Docker image where only /tmp is writable -- mount a
volume at the cache dir to persist it).
