BaaRai 0116786f02 Fix review: dalfox --rate-limit/--workers, drop passive subfinder -t
Dalfox v3.2.4 (Rust) has no -w and exposes a global --rate-limit plus --workers (docs/content/reference/cli.md). Subfinder -t only bounds concurrent DNS lookups in active mode, so the passive line is removed; the generic fallback covers it.
