主要解决问题：
当 wait_tx_confirmed 参数为 false 时，SUBMIT_TIMEOUT_SECS 等待改为2秒，要么全部提交完成返回，要么不等待提交未返回的交易，方便快速创建交易订单。
#Let the SDK print submit_timing data (SwqosType and submission time) and return it to the buy and sell methods.
Main problems solved:
When the wait_tx_confirmed parameter is false, the SUBMIT_TIMEOUT_SECS wait is changed to 2 seconds. Either all submissions are completed and returned, or the unreturned transactions are not waited for submission, which facilitates the rapid creation of transaction orders.
- Introduce DexParamEnum to replace Dex enum for protocol parameters
- Simplify TradeConfig::new() to accept only 3 essential parameters
- Update all examples to use new DexParamEnum API
- Optimize executor and params modules
- Remove deprecated wsol_use_seed and mint_use_seed parameters
- Fix fast_fn module exports
Major changes:
- Bump version from 3.3.0 to 3.3.1
- Update GasFeeStrategy API with min/max data size parameters
- Enhance trade return values with Optional<anyhow::Error> in buy/sell/sell_percent methods
- Fix PumpFun Mayhem mode fee recipient constant bug
- Standardize gas fee strategy parameters across all examples
- Update all examples to handle new triple return value (bool, Signature, Option<Error>)
- Bump version from 1.2.0 to 1.2.1
- Change trade methods return type from Signature to (bool, Signature)
- Improve parallel execution error handling and status tracking
- Update CLI examples to match new API interface
- Enhance transaction success/failure reporting capabilities
Breaking Change: Trade API now returns tuple (success_status, signature)
- Merge BuyParams and SellParams into unified SwapParams structure
- Add USD1 token pool support with related constants and configurations
- Refactor trade executor by combining buy_with_tip and sell_with_tip into swap method
- Update all protocol instruction builders to support new parameter structure
- Standardize ATA creation/closing parameter naming conventions
- Update example code to use new API interfaces
- Optimize trading logic with automatic direction detection based on input token type
- Simplify TradeExecutor interface by integrating middleware and swqos clients into params
- Refactor parallel execution module with dedicated buy/sell execute functions
- Add SOL wrapping/unwrapping functionality for wSOL management
- Remove redundant parameter passing in sell operations
- Delete example main.rs file
- Optimize transaction building with integrated parameter structures
BREAKING CHANGE: TradeExecutor interface simplified, middleware and swqos_clients now passed through params
- Remove redundant transaction builder functions and merge into single build_transaction()
- Simplify compute budget manager with unified add_compute_budget_instructions()
- Consolidate trade executor interface by removing separate buy/sell methods
- Unify BuyParams/SellParams usage, remove *WithTipParams structs
- Streamline parallel execution logic and remove TradeType parameter
- Delete obsolete files: address_lookup.rs, tip_cache.rs
- Clean up nonce manager by removing unused is_using_nonce() function
This refactoring reduces code duplication and provides a cleaner, more maintainable API
for transaction building and execution across all trading protocols.
- Add unified TradeExecutor interface and protocol abstraction
- Refactor PumpFun/PumpSwap into adapter pattern
- Introduce TradeFactory for multi-protocol support
- Add parallel execution and unified parameter system
- Include Raydium protocol support and log parsing
- Simplify codebase structure and improve maintainability
