rockerBOO e03200bdba Optimize: Cache CDC shapes in memory to eliminate I/O bottleneck ...

- Cache all shapes during GammaBDataset initialization
- Eliminates file I/O on every training step (9.5M accesses/sec)
- Reduces get_shape() from file operation to dict lookup
- Memory overhead: ~126 bytes/sample (~12.6 MB per 100k images)
