/**
* @file hybrid_search_comprehensive_test.cpp
* @brief Integration tests for SearchEngine (PBI-071, updated for PBI-091)
*
* Integration test coverage focusing on:
* - Multi-component search (FTS5, vector, symbol, KG, path tree)
* - Fusion strategies (WEIGHTED_SUM, RECIPROCAL_RANK, WEIGHTED_RECIPROCAL, COMB_MNZ)
* - Fallback scenarios (degraded mode, timeouts)
* - Real component integration (actual indexes, engines)
* - Performance characteristics
*
* Note: This is an integration test, not a unit test. It uses real
* components rather than mocks to validate end-to-end behavior.
