UbuntuandCursor 206b27fe72 refactor: 以自实现指标替换 talib 与 technical 依赖 
chanlun/indicators/ta.py 接口兼容 talib.abstract，实现代码实际用到的
SMA/MA/EMA/RSI/ATR/MACD/BBANDS；chanlun/pipeline/resample.py 替代
technical.util.resample_to_interval。调用点只改 import，逻辑未动。

暖机长度与平滑种子按 TA-Lib 的约定实现，差一根 K 线就会让下游所有
笔/线段/中枢整体位移。其中 MACD 需特别处理：TA-Lib 让快慢两条 EMA
在同一根 K 线出首值，因而快线的种子取 x[slow-fast:slow] 的均值，而非
从 fastperiod-1 一路递推——两者在百元价位上相差约 0.17。

BBANDS 是有意的分歧：TA-Lib 用 sumsq/n - mean² 求方差，短窗口远离零
时灾难性抵消（timeperiod=2 误差 8.7e-7），本实现用 rolling std，对 50
位精度基准误差为 0。项目实际使用的周期两者一致到 1e-10。

顺带清理 12 个文件中 16 处从未调用的 talib/technical 导入。

验证：9440 组随机对拨；真实 K 线端到端比对 add_indicators 全部 33 个
指标列，NaN 模式一致、MACD 柱符号 100% 相同；屏蔽两个包后 60 个模块
均可导入。新增 test_ta_compat.py 将输出逐 bar 钉在 TA-Lib 上，但该文件
在 TA-Lib 缺失时静默跳过，改动 ta.py 需在装有 TA-Lib 的环境复跑。
