fix: Optimize fuzzing and fix CSV buffer accumulation

- Deploy Uniswap factory once before all runs (saves ~1.16M gas per run)
- Fix CSV buffer accumulation bug by clearing buffer between runs
- Add clearCSV() function to CSVManager for proper buffer management
- Each fuzzing run now gets its own clean CSV with correct token0isWeth values
- Comment out failing console.log in Optimizer.t.sol to fix compilation

The token ordering now correctly alternates:
- Even seeds: token0isWeth = true (WETH < KRAIKEN)
- Odd seeds: token0isWeth = false (KRAIKEN < WETH)
