pykrx get_market_ohlcv returns 6 data columns (시가/고가/저가/종가/거래량/거래대금),
not 7. The 등락률 (change) column does not exist, causing a length mismatch error.

The pykrx library uses 'etx' not 'etf' as the module directory name,
and fetch() is the proper method that returns a DataFrame.

KRX CSV download endpoint blocks requests from cloud/server IPs,
causing "No columns to parse from file" errors. Replaced with pykrx's
JSON-based API (get_market_ticker_list, get_market_cap_by_ticker,
get_market_fundamental_by_ticker) which is more reliable.
