Improve crash recovery diagnostics and analysis
- Expanded the crash recovery module to include advanced diagnostic metrics such as system entropy, KL-Divergence, and manifold curvature. - Improved root cause analysis by implementing a probabilistic approach with detailed suggestions for various failure scenarios. - Added comprehensive tests to validate heuristic analysis, entropy calculations, and the robustness of the crash recovery logic. - Updated existing tests to ensure accurate diagnosis and reporting of system states during exceptions.
