feat: pass is_cashback_coin from events; PumpFun examples use sol-parser-sdk only

Browse Source 
- PumpFunParams/BondingCurve: from_trade/from_dev_trade take is_cashback_coin parameter
- pumpfun_copy_trading and pumpfun_sniper_trading use sol-parser-sdk for gRPC, pass e.is_cashback_coin
- address_lookup/nonce_cache call sites updated; README EN/CN Cashback and example notes

//! PumpFun 狙击示例（仅使用 sol-parser-sdk 订阅 gRPC 事件）
//!
//! 监听创建者首次买入（Create 后同笔/首笔 Buy，is_created_buy == true），
//! 用事件参数（含 is_cashback_coin）构造 from_dev_trade 并执行一次买+卖。
