/**
 * Semantic Enhancement Engine for Tool Discovery
 *
 * INDUSTRY PURPOSE: Addresses semantic gaps in vector-based tool discovery through
 * two complementary enhancement mechanisms:
 *
 * 1. CAPABILITY INFERENCE SYSTEM (Global Domain Knowledge)
 *    - Infers implicit capabilities from tool categories/types
 *    - Example: shell MCP → can perform git, docker, ffmpeg operations
 *    - Fills knowledge gaps that vector similarity cannot capture
 *
 * 2. SEMANTIC INTENT RESOLUTION (Context-Specific Language Mapping)
 *    - Maps natural language expressions to domain-specific operations
 *    - Example: "upload my code" → git:push, github:create_repository
 *    - Resolves contextual language that differs from tool naming
 *
 * This follows established NLP/IR patterns for query expansion and semantic matching.
