Transfer Logic with Fees and Cycles

The `_transfer` function applies fees, checks cycles, and processes rewards:

// ```solidity
function _transfer(address _from, address _to, uint256 _value) internal returns (bool) {
    // ... require checks ...

    // Cycle check and adjust supply
    if (block.timestamp > last_turnTime + 60) {
        if (_totalSupply >= max_supply) {
            isBurning = true;
            _turn();
            // Burn excess
        } else if (_totalSupply <= min_supply) {
            isBurning = false;
            _turn();
            // Mint to pool
        }
    }

    // Apply fees based on burning state
    if (isBurning) {
        uint256 burn_amt = _pctCalc_minusScale(_value, burn_pct);
        // ... burn, treasury, rewards pool transfers ...
    } else {
        uint256 mint_amt = _pctCalc_minusScale(_value, mint_pct);
        // ... mint, treasury, rewards pool transfers ...
    }

    // Update last TX times and process eligibility
    lastTXtime[tx.origin] = block.timestamp;
    lastTXtime[_from] = block.timestamp;
    lastTXtime[_to] = block.timestamp;
    rewardProcess(_value, tx.origin, _from, _to);  // Accumulate rewards eligibility

    return true;
}
```
