Every setting of waf and rproxy is read through viper, in place of the os.LookupEnv function Main passed down. NewViper turns AutomaticEnv and AllowEmptyEnv on, so a setting that is set but empty reads as set. A setting may also be given as a file, the _FILE form, which rproxy's settings now have too; rproxy still writes nothing to disk. The settings are renamed: waf's take the prefix SWW_WAF_, rproxy's take SWW_RPROXY_, and the shared SWW_COMMAND keeps SWW_. The Core Rule Set's settings take SWW_WAF_CORE_RULE_SET_ rather than SWW_WAF_WAF_. Model: deepseek-v4-pro (first version); opus-5-5 (rework)
