feat: v3.5 - Multi-language acoustic algorithm scheduler

- Core: Python/C++/MATLAB tri-protocol bridge architecture
- Validation: 5-type real-time field, type, dimension, completeness, and compatibility checking
- UI: Premium Deep Sea theme with visual pipeline preview
- Modules: Sea Trial Exclusive + Exception Hub + Algorithm Management
- Tests: Full coverage with 5 automated test cases
