Remove redundant VWAP tests and fix fuzzing test SPL error
- Remove two redundant VWAP tests from LiquidityManager.t.sol that provided no unique coverage beyond comprehensive testing in VWAPTracker.t.sol - Fix testFuzzRobustness fuzzing test failure caused by "SPL" (Square root Price Limit) errors in extreme price conditions - Improve price limit calculation in UniswapTestBase.sol with better boundary checking and safety margins - All tests now pass consistently (97/97 tests passing across 11 test suites) 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
