* feat(fasthttpproxy): add dual-stack connection support to enable IPv6 proxies for HTTP and SOCKS5 dialers

- Added `FasthttpHTTPDialerDualStack` to support dual-stack (IPv4 and IPv6) connections for HTTP proxies, enabling IPv6 proxy usage.
- Added `FasthttpSocksDialerDualStack` to support dual-stack (IPv4 and IPv6) connections for SOCKS5 proxies, enabling IPv6 proxy usage.
- Improved dialer configuration to ensure compatibility with both IPv4 and IPv6 proxies.

* fix(lint): address linting issues in code
