Module pool 

Multi-source entropy pool with health monitoring.

Architecture:

1. Auto-discover available sources on this machine
2. Collect raw entropy from each source in parallel
3. Concatenate source bytes into a shared buffer
4. Apply conditioning (Raw / VonNeumann / SHA-256) on output
5. Continuous health monitoring per source
6. Graceful degradation when sources fail
7. Thread-safe for concurrent access

Structs

EntropyPool

Thread-safe multi-source entropy pool.

HealthReport

Overall health report for the entropy pool.

SourceHealth
