Env is environment, Config is ours. Provides centralised access to system facts (OS, ARCH, hostname, user, directories, timestamps) via string key lookup, populated once at package init. Keys: OS, ARCH, GO, DS, PS, HOSTNAME, USER, PID, NUM_CPU, DIR_HOME, DIR_CONFIG, DIR_CACHE, DIR_DATA, DIR_TMP, DIR_CWD, DIR_DOWNLOADS, DIR_CODE, CORE_START. 17 tests covering all keys + unknown key + Core instance accessor.
