Document the practical workflow for detecting and diagnosing memory
leaks in U-Boot, particularly in sandbox builds. This covers:
- Using ut_check_delta() in unit tests for leak detection
- Comparing heap dumps with malloc_dump_to_file()
- Using malloc traffic logging to trace allocations
- Verifying debug functions don't affect heap state
- A step-by-step practical workflow
