- New _PER_SYMBOL_TFS map in signal_aggregator routes gold/silver to
M15+H1+H4 confirmation; forex pairs untouched.
- H4 for XAU/XAG is resampled from yfinance H1 bars (yfinance has no
native 4h candle). New _resample_h1_to_h4 helper.
- Batch prefetch unions per-symbol TFs so future per-pair overrides
work without extra plumbing. XAU/XAG still excluded from Twelve Data
batch — H4 resample triggers a single yfinance H1 fetch.
- Telegram SCAN_TIMEFRAMES restored to [M15, H1] so /scan emits both
M15-primary and H1-primary cards. Shared cache means no extra credits.

- telegram_bot: one ForexDataProvider shared across all SCAN_TIMEFRAMES;
combined prefetch of all unique TFs up front so the 4 concurrent scans
hit the warm cache instead of firing simultaneous API calls
- data_provider: skip prefetch_batch for timeframes already in cache
- data_provider: deduplicate "no data" warning per symbol (fires once, not once per TF)
- data_provider: [live] info log on successful fetch; outlier-removal downgraded to debug

- 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
