# Script to create a Uniswap V3 pool for eSILVST token and add initial liquidity
# This script performs the following steps:
# 1. Mint tokens to the owner's address
# 2. Create a Uniswap V3 pool
# 3. Initialize the pool with a price
# 4. Approve the Position Manager to spend tokens
# 5. Add liquidity to the pool
