GitHub 615994ad72 feat(kline): 分钟级K线时间戳可选bar_time对齐Tushare (Discussion #7) 
通达信协议用bar开始时间打时间戳（5min线上午最后一根标11:25、下午第一根标13:00；午休11:30-13:00无bar），而Tushare/同花顺/聚宽用bar结束时间（标11:30/13:05）。新增bar_time参数让用户一键切换，避免自行+5分钟偏移。

- 全部3条K线路径覆盖：A股get_security_bars/get_index_bars、扩展行情get_instrument_bars、MAC get_stock_kline（含同步+异步、get_stock_kline_with_indicators）

- CLI kline新增--bar-time {start,end}选项；Web /bars、/bars/index新增bar_time查询参数

- bar_time=start（默认）保持完全向后兼容；bar_time=end仅对分钟级周期（1/5/15/30/60min）生效，自动按周期时长右移并处理跨小时/跨日边界

- 协议解码层零改动，偏移作为纯展示语义在client层后处理，单一工具函数_apply_bar_time_align_df/_apply_bar_time_align_bars复用于全部路径

- 新增27个单元测试（test_codec_datetime.py偏移逻辑 + test_kline_bar_time.py三路径覆盖），全量700单测通过

- bump 版本号至 1.16.0
