- 将臃肿的 parse.go 按职责拆分为多个模块：
parse_types.go、parse_io.go、parse_event_convert.go、parse_stream.go、parse_filter.go
- parse.go 保留为模块入口说明，提升可维护性与可读性
- 修复事务状态被覆盖问题（BEGIN/COMMIT/ROLLBACK 不再被重置为 PREPARE）
- 增加 include-tables 与 exclude-tables 互斥校验，同时配置时直接报配置错误
- 强化表匹配器模式校验，并补充非法模式测试
- 在明细过滤后重算事务统计（RowsCount/StartPos/EndPos/Size），避免统计失真
- 增加 TABLE_MAP 事件转换，补充列元信息透传（ColumnTypes/ColumnCollationIDs）
- 基于 unsigned 元数据规范化行值，避免无符号整型被渲染为负数
- 优化事件解析报错信息：增加有界 body 十六进制预览
- 补充单元测试：payload/tablemap 转换、unsigned 规范化、过滤逻辑、IO 预览
