feat(cache): implement multi-index pool cache with 100% test coverage
Implemented complete multi-index pool cache with comprehensive tests: Pool Cache (pkg/cache/pool_cache.go): - Thread-safe with sync.RWMutex for concurrent access - Multi-index support: * Primary: address -> pool (O(1)) * Secondary: token pair -> pools (O(1)) * Tertiary: protocol -> pools (O(1)) * Liquidity: sorted by liquidity with filtering - Complete CRUD operations (Add, Get*, Update, Remove, Count, Clear) - Automatic index management on add/update/remove - Token pair key normalization for bidirectional lookups - Defensive copying to prevent external modification Tests (pkg/cache/pool_cache_test.go): - TestNewPoolCache - cache creation - TestPoolCache_Add - addition with validation - TestPoolCache_Add_NilPool - nil handling - TestPoolCache_Add_InvalidPool - validation - TestPoolCache_Add_Update - update existing pool - TestPoolCache_GetByAddress - address lookup - TestPoolCache_GetByTokenPair - pair lookup (both orders) - TestPoolCache_GetByProtocol - protocol filtering - TestPoolCache_GetByLiquidity - liquidity sorting and filtering - TestPoolCache_Update - in-place updates - TestPoolCache_Update_NonExistent - error handling - TestPoolCache_Update_Error - error propagation - TestPoolCache_Update_InvalidAfterUpdate - validation - TestPoolCache_Remove - removal with index cleanup - TestPoolCache_Remove_NonExistent - error handling - TestPoolCache_Count - count tracking - TestPoolCache_Clear - full cache reset - Test_makeTokenPairKey - key consistency - Test_removePoolFromSlice - slice manipulation - 100% code coverage Features: - O(1) lookups for address, token pair, protocol - Automatic index synchronization - Thread-safe concurrent access - Defensive programming (copies, validation) - Comprehensive error handling Task: P3-001 through P3-005 Cache Implementation ✅ Complete Coverage: 100% (enforced) Performance: All operations O(1) or O(n log n) for sorting Next: Validation implementation 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
