Generic Composite Validator for Multi-Round Interaction Problems

This validator handles composite problems by:
1. Supporting multi-round interaction results
2. Validating error reports (if LLM detects issues)
3. Validating task completion (checking final chain state)
4. Checking parameter compliance (CRITICAL: no unauthorized modifications)
5. Modular scoring using atomic validator components
