Does not detect tokens, neither at startup nor after swap

[ra549243]

Does not detect LAUNCHCOIN tokens that might already be in the wallet at startup. Proceeds to swap some SOL and still doesn't detect the swapped LAUNCHCOIN, causing it to create a single sided position (SOL only).

This fixes the second part (workaround - there's a problem with fetchBalances apparently):

// Fix: Get actual token balance from swap transaction (Jupiter uses different ATA)
const txInfo = await connection.getParsedTransaction(sig, { 
  maxSupportedTransactionVersion: 0, commitment: 'confirmed' 
});

if (txInfo?.meta?.postTokenBalances) {
  const myOutputBalance = txInfo.meta.postTokenBalances.find(
    balance => balance.mint === outputMint && 
               balance.owner === userKeypair.publicKey.toString() &&
               balance.uiTokenAmount.amount !== '0'
  );
  
  if (myOutputBalance) {
    const actualTokenBalance = new BN(myOutputBalance.uiTokenAmount.amount);
    
    // Update balance directly instead of using fetchBalances for swapped token
    if (outputMint === X_MINT) {
      lamX = actualTokenBalance;
      lamY = (await fetchBalances(connection, dlmmPool, userKeypair.publicKey)).lamY;
    } else {
      lamY = actualTokenBalance;
      lamX = (await fetchBalances(connection, dlmmPool, userKeypair.publicKey)).lamX;
    }
  }
} else {
  // Fallback to regular balance fetching if transaction parsing fails
  ({ lamX, lamY } = await fetchBalances(connection, dlmmPool, userKeypair.publicKey));
}
