Module tool_result 

Tool execution result with cryptographic verification

This module provides the ToolResult type which wraps tool output with a SHA-256 hash for Merkle tree integration.

VEX Innovation

Every tool execution result is automatically hashed, enabling:

• Cryptographic proof of tool execution
• Merkle tree integration for audit trails
• Tamper-evident logging

Security Considerations

• Hash includes timestamp to prevent replay attacks
• Deterministic serialization ensures consistent hashing
• Output is NOT sanitized here (responsibility of the tool)

Structs
