插件特征 定义插件的核心行为，包括事务处理和过滤功能

Provided Methods

fn metadata(&self) -> PluginMetadata

获取插件元数据（静态信息）- 提供默认实现

fn config(&self) -> PluginConfig

获取插件配置（静态配置）- 提供默认实现

fn append_transaction<'life0, 'life1, 'life2, 'life3, 'async_trait>( &'life0 self, _: &'life1 [Transaction], _: &'life2 State, _: &'life3 State, ) -> Pin<Box<dyn Future<Output = Result<Option<Transaction>, Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, 'life3: 'async_trait, Self: 'async_trait,

追加事务处理 允许插件在事务执行前修改或扩展事务内容

fn filter_transaction<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, _: &'life1 Transaction, _: &'life2 State, ) -> Pin<Box<dyn Future<Output = bool> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, Self: 'async_trait,

事务过滤 决定是否允许事务执行
