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>

* @title LiquidityManager for Kraiken Token on Uniswap V3
|
||||
* @notice Manages liquidity provisioning on Uniswap V3 for the Kraiken token by maintaining three distinct positions:
|
||||
* - Floor Position: Ensures a minimum price support by having enough reserve assets to potentially buy back the circulating supply of Kraiken.
|
||||
* - Anchor Position: Provides liquidity around the current market price to facilitate trading and maintain market stability.
|
||||
* - Discovery Position: Expands liquidity by minting new Kraiken tokens as the price rises, capturing potential growth in the ecosystem.
|
||||
* The contract dynamically adjusts these positions in response to market movements to maintain strategic liquidity levels and support the Kraiken token's price.
|
||||
* It also collects and transfers fees generated from trading activities to a designated fee destination.
|
||||
* @dev Utilizes Uniswap V3's concentrated liquidity feature, enabling highly efficient use of capital.
|
||||
* @title LiquidityManager
|
||||
* @notice Manages liquidity provisioning on Uniswap V3 using the three-position anti-arbitrage strategy
|
||||
* @dev Inherits from modular contracts for better separation of concerns and testability
