fix(minervini): cap ticker universe to prevent CI timeout

yf.download(592 tickers, period=1y) takes 20+ minutes in CI, causing
the 30-minute job timeout to trigger. Add max_tickers=200 (configurable)
to limit the batch download to the first N tickers from the file. The
concurrent scanner pool already has a 5-min global timeout, but the hung
download thread monopolises network connections and starves the filter stage.
