17// MintAndStake mints a new liquidity position and immediately stakes it.
18//
19// Atomic operation combining position creation and staking.
20// Saves gas by avoiding separate mint and stake transactions.
21// Position NFT transferred directly to staker contract.
22//
23// Parameters:
24//   - token0, token1: Token contract paths
25//   - fee: Pool fee tier (500=0.05%, 3000=0.3%, 10000=1%)
26//   - tickLower, tickUpper: Price range boundaries
27//   - amount0Desired, amount1Desired: Target token amounts
28//   - amount0Min, amount1Min: Minimum amounts (slippage protection)
29//   - deadline: Transaction expiration timestamp
30//   - referrer: Optional referral address
31//
32// Native token support:
33//   - Accepts GNOT via std.OriginSend()
34//   - Auto-wraps to WUGNOT for liquidity
35//   - Minimum 1 GNOT required
36//
37// Returns:
38//   - positionId: New NFT token ID
39//   - liquidity: Amount of liquidity minted
40//   - amount0, amount1: Actual tokens deposited
41//   - poolPath: Pool identifier
