feat: US-002 - YAML-based Attack Rule System
Implement a YAML-based rule system for defining attack patterns and success conditions, inspired by Promptmap's 50+ YAML rule definitions. Features: - AttackRule model with name, type, severity, prompt, pass/fail conditions - RuleLoader for parsing YAML files with validation - Support for recursive directory loading and filtering by type/severity - Template variable substitution in prompts - Dataset integration for converting rules to ProbeDataset format - YAMLRulesDatasetLoader for loading rules from multiple directories Tested with 47 unit tests covering models, loader, and dataset integration. Successfully loads 69 rules from promptmap research directory.
