Administrator 6c85906b56 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
