ChanPivotMonitor: 实时中枢特征跟踪 + Telegram推送

- ChanPivotClassifier: 提取 calc_duration/contraction/shift 为 @staticmethod，新增 compute_features()
- ChanPivotMonitor: 实时追踪当前中枢，bi_count 增长时重新计算 shift/contraction/duration
- bsp_monitor/fetcher: 改用 data_provider HTTP API 替代直连 CCXT
- bsp_monitor/notify: 新增 send_telegram_message() 通用推送
- bsp_monitor/main: 集成 ChanPivotMonitor，有新笔或 BSP 时推送到 Telegram
