feat(JEPA/math): 新增专题 VII & VIII，更新 README 与项目分析
...
Sync to site1 / sync (push) Has been cancelled
专题 VII — SIGReg 正则化（07_sigreg_regularization.md，760 行）
- 特征函数匹配损失 L_SIG 完整数学推导
- Cramér-Wold 定理证明：切片投影 → 联合高斯
- 切片技巧：256 个随机方向 + 梯形积分（17 节点）
- losses.py:SIGReg 逐行代码解析，张量形状追踪 (V,B,N)→scalar
- vs VICReg 对比：SIGReg 约束全分布，VICReg 仅约束二阶矩
专题 VIII — 线性 ICA：FastICA 与 JADE（08_linear_ica_fastica_jade.md，701 行）
- 盲源分离模型 x=As，非高斯性度量（峰度/负熵/互信息）
- FastICA 不动点迭代推导（三次收敛）
- JADE 四阶累积量张量 + Jacobi 联合对角化（二次收敛）
- Darmois-Skitovich 定理：ICA 可识别性充要条件
- ICA vs LeJEPA 对偶反转：高斯在 ICA 失败，在 LeJEPA 成功
其他变更：
- JEPA/math/README.md：专题表格新增 VII、VIII 行
- project_analysis.md：Session Log 补充 2026-06-05 工作记录
- lejepa-identifiability 子模块：.gitignore 新增 .venv/

Add detailed lecture plan and summary for LeJEPA four theorems
...
- Introduced a comprehensive lecture plan for the four main theorems in LeJEPA, including knowledge dependency graphs, detailed outlines for each topic, and corresponding Lean 4 files for formal verification.
- Created a summary document encapsulating the core insights and mathematical structures of the four theorems, emphasizing their interdependencies and implications in the context of LeJEPA.
