fix(web): 自动刷新保留 K 线视窗；威科夫与图表增量更新

自动刷新改用 tail update 与 scrollToPosition 恢复视窗，避免 setData 后跳到最右；拆分 chart_tv 模块并扩展 analyze/recent API。同步威科夫分析、pipeline 增量构建及相关策略与配置。 Co-authored-by: Cursor <cursoragent@cursor.com>

+# Wyckoff BTC System v1 — Decision Rule Locked
+
+```
+Architecture: Market State → Decision → Signal
+
+Spring:          FROZEN
+Gate v1.1:       LOCKED DEFAULT Decision rule  (PASS)
+Soft-score:      REJECTED (no increment)
+Hard-score:      REJECTED
+
+Minimal rule:
+  market_state in {accumulation, markup} -> allow Spring
+  else -> block Spring
+
+Primary invalidation domain: distribution
+range: observation bucket only (NOT a trading rule)
+
+Validity: DEFINED
+Confidence: MEDIUM / defined-domain PASS
+Status: DEFAULT RULES FROZEN
+Next: dry-run / monitoring only（见 operational checklist）
+```
+
+## Operational
+
+上线前不改规则，只验执行链：
+
+→ [`DRY_RUN_DECISION_CHECKLIST.md`](./DRY_RUN_DECISION_CHECKLIST.md)
+
+覆盖：信号一致性 · 日志字段 · dry-run 监控 · 报警 · 硬禁 · Go/No-Go。
+
+## Locked stack
+
+| Layer | File | Status |
+|-------|------|--------|
+| Signal | `Wyckoff_BTC_V1_BASELINE.py` | FROZEN |
+| State | `engine/market_state.py` | causal v1.1 |
+| Decision | `Wyckoff_BTC_GATED.py` | **LOCKED state_set** |
+| Boundary | `VALIDITY_BOUNDARY.md` | active |
+
+## Robustness slices (blocked Spring, by year/era)
+
+证据：`scripts/wyckoff_gate_robustness_slices_result.json`
+
+| Slice | blocked n | dist share | top blocked | blocked PF |
+|-------|-----------|------------|-------------|------------|
+| 2020 | 3 | **1.00** | distribution | 0.73 |
+| 2021 | 4 | **0.75** | distribution | 0.31 |
+| 2022 | 1 | 1.00 | distribution | 0 |
+| 2023 | 1 | 1.00 | distribution | 0 |
+| 2024 | 3 | 0.33 | distribution+range | 0 |
+| 2025 | 1 | 0 | range (obs) | n=1 win |
+| pre_2023 | 8 | **0.875** | distribution | 0.37 |
+| 2023plus | 5 | 0.40 | distribution+range | 1.22 |
+
+Verdict: **distribution 归因在多数有样本切片上稳定**（PASS）。  
+2023+ / 2024–25 中 range 占比上升 → 保持 **观察标签**，不升格为交易规则。
+
+## Do not
+
+- 调 Spring / soft-score / Gate 阈值  
+- 因 range 小样本正 PF 开放 range 交易  
+- 复活 LPS / 默认跨资产
