Observation: Overshoot buffer doesn't fully cover slippage tolerance (Uniswap V4)

In UniswapV4FundingPlanner.ts, the withdrawal adds a 0.05% (5 bps) overshoot buffer to the target amount:

const bufferedRemaining = remaining + (remaining * 5n) / 10_000n

But the slippage tolerance is set to 0.10% (10 bps):

const SLIPPAGE_TOLERANCE = new Percent(10, 10_000) // 0.10%

This means in the worst case:

• Need 100 tokens
• Withdraw 100.05 (buffered)
• Slippage hits the full 0.10% → receive ~99.95
• Transaction succeeds but you're 0.05 short of what's actually needed

The buffer doesn't fully cover the slippage tolerance. If slippage exceeds 0.05%, the withdrawal succeeds but the subsequent fill could fail due to insufficient funds.

Consider either increasing the buffer to match or exceed the slippage tolerance, or reducing the slippage tolerance to match the buffer.
