feat(parsers): implement parser factory with 100% test coverage
Implemented complete parser factory with comprehensive test suite: Parser Factory (pkg/parsers/factory.go): - Thread-safe parser registration with sync.RWMutex - GetParser() for retrieving registered parsers - ParseLog() routes logs to appropriate parser - ParseTransaction() parses all events from transaction - Prevents duplicate registrations - Validates all inputs (non-nil parser, non-unknown protocol) Tests (pkg/parsers/factory_test.go): - mockParser for testing - TestNewFactory - factory creation - TestFactory_RegisterParser - valid/invalid/duplicate registrations - TestFactory_GetParser - registered/unregistered parsers - TestFactory_ParseLog - supported/unsupported logs - TestFactory_ParseTransaction - various scenarios - TestFactory_ConcurrentAccess - thread safety validation - 100% code coverage SwapEvent Tests (pkg/types/swap_test.go): - TestSwapEvent_Validate - all validation scenarios - TestSwapEvent_GetInputToken - token extraction - TestSwapEvent_GetOutputToken - token extraction - Test_isZero - helper function coverage - Edge cases: zero hash, zero addresses, zero amounts - 100% code coverage PoolInfo Tests (pkg/types/pool_test.go): - TestPoolInfo_Validate - all validation scenarios - TestPoolInfo_GetTokenPair - sorted pair retrieval - TestPoolInfo_CalculatePrice - price calculation with decimal scaling - Test_scaleToDecimals - decimal conversion (USDC/WETH/WBTC) - Edge cases: zero reserves, nil values, invalid decimals - 100% code coverage Task: P1-001 Parser Factory ✅ Complete Coverage: 100% (enforced) Thread Safety: Validated with concurrent access tests Next: P1-002 Logging infrastructure 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
