- yfinance>=0.2.40 added as a hard dependency
- _fetch_yfinance_fallback(): pulls OHLCV from Yahoo for symbols not on
the Twelve Data free tier (XAUUSD → GC=F, XAGUSD → SI=F)
- Hooked into both batch and single-symbol fetch paths; logs as [yf]
to distinguish from Twelve Data [live]
- Fail-loud: if both providers return nothing, the pair is skipped with
the existing "data unavailable" message
- _analyze_all_tfs accepts an async progress callback; both /signal and
/scan now show coarse milestones via message edits:
"📡 Fetching market data..." → "🧠 Analyzing pairs..." → result
- prefetch_batch is now run in a thread so it doesn't block the event loop

- Add telegram_bot.py: full bot interface with /scan, /signals, /pair,
/all, /tf, /watch, /unwatch, /status, /help commands; per-chat state;
background thread pool for analysis; auto message splitting
- Fix data_provider: warn once per symbol with no API data and cache
synthetic fallback to prevent redundant individual API calls
- Fix signal_aggregator: derive spread estimate from already-fetched
primary DataFrame instead of making a separate M5 API call per pair
- Add python-telegram-bot[job-queue]>=20.0 to requirements.txt
