/**
 * Contract Extractor for MAMA v2 (TypeScript Port)
 *
 * Extracts API contracts, function signatures, and type definitions
 * from code changes using simple pattern matching.
 *
 * Design Philosophy:
 * - Simple regex patterns for common cases (80% coverage)
 * - Main Claude handles complex cases (20%)
 * - Transparent: All extractions visible to Main Claude
 *
 * Ported from: packages/claude-code-plugin/src/core/contract-extractor.js
