feat: implement related nonce attack

[oritwoen]

Description

Detect and exploit predictable/related nonce sequences.

Background

When nonces follow predictable sequences (incrementing, XOR patterns, simple transformations), the relationship between consecutive nonces can be exploited for key recovery.

Requirements

• Detect common nonce relationships:
  • Incrementing: k_{n+1} = k_n + 1
  • XOR patterns: k_{n+1} = k_n ^ constant
  • Multiplication: k_{n+1} = k_n * constant
• Exploit detected relationships for key recovery

Technical Notes

• Overlaps with LCG detection (LCG is a specific case)
• May need heuristics to detect unknown patterns
• Consider statistical tests for relationship detection
