Replace all os.ReadFile/os.WriteFile/os.MkdirAll in production code with
coreio.Local equivalents (Read, Write, EnsureDir) from go-io. Replace all
fmt.Errorf and errors.New with coreerr.E() from go-log, adding structured
operation context to all error returns. Promote go-log from indirect to
direct dependency in go.mod.
