feat: massively expand crypto sentiment vocabulary (v2)

- CRYPTO_BULLISH_KEYWORDS: ~200+ terms covering price action, institutional/ETF, exchange listings, partnerships, technical indicators, on-chain, DeFi yield, macro narratives, sentiment/social
- CRYPTO_BEARISH_KEYWORDS: ~350+ terms covering crashes/dumps, liquidations, hacks/exploits, depeg, outflows/selling, regulatory/legal, bankruptcy, technical indicators, on-chain, DeFi issues, macro risk-off, sentiment/social
- WHALE_BULLISH_PHRASES: ~55+ context-aware phrases for whale/smart money/large holder accumulation
- WHALE_BEARISH_PHRASES: ~75+ context-aware phrases for whale/smart money/large holder distribution

Fixed critical crypto terminology:
- Exchange OUTFLOWS -> bullish (coins leaving to cold storage)
- Exchange INFLOWS -> bearish (coins entering to sell)
- Bank run / solvency concerns -> bearish
- Withdrawal spikes -> bearish (user exodus), whale withdrawals -> bullish

Result: 15/15 critical sentiment tests pass, 14/16 edge case tests pass, 90/91 NLP pipeline tests pass (1 pre-existing failure).
