Subject: [PATCH] fix: fs.go use Result{}.Result() return value, i18n uses
 i.locale
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

fs.go: Value receiver Result() returns new Result — must use return
value not discard it. Changed from r.Result(...); return *r to
return Result{}.Result(os.ReadDir(...)).

i18n: SetLanguage sets i.locale directly. Language() reads i.locale.
Translator reload is core/go-i18n's responsibility.

231 tests passing.
