feat: massively expand crypto sentiment vocabulary

- 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: ~50+ context-aware phrases for whale accumulation/buying
- WHALE_BEARISH_PHRASES: ~70+ context-aware phrases for whale distribution/selling

Both keyword lists duplicated in CryptoSentimentCalibrator class for backward compatibility.

Result: 15/15 critical sentiment tests still pass with vastly expanded coverage.
