Youssef Aitousarrah e15e2df7a5 feat(cache): unified ticker universe + nightly OHLCV prefetch
- tradingagents/dataflows/universe.py: single source of truth for ticker
  universe; all scanners now call load_universe(config) instead of
  duplicating the 3-level fallback chain with hardcoded "data/tickers.txt"

- scripts/prefetch_ohlcv.py: nightly script using existing ohlcv_cache.py
  incremental logic; first run downloads 1y history, subsequent runs append
  only new trading days

- .github/workflows/prefetch.yml: runs at 01:00 UTC daily, before all other
  workflows; commits updated parquet to repo

- Updated 6 scanners: minervini, high_52w_breakout, ml_signal, options_flow,
  sector_rotation, technical_breakout — removed duplicate DEFAULT_TICKER_FILE
  constants and _load_tickers_from_file() functions

- minervini, high_52w_breakout, technical_breakout: replace yf.download()
  with download_ohlcv_cached() — reads from prefetched cache instead of
  hitting yfinance at discovery time

- default_config.py: added discovery.ohlcv_cache_dir config key

- data/ohlcv_cache/: initial 1y backfill (588 tickers, 5.4MB parquet)
