574bcf2264 FRE-4521 Implement Redis integration for rate limiting and deduplication
- Add ioredis dependency for Redis connection pooling
- Create RedisService singleton with connection management
- Add Redis config (url, dedupWindowSeconds) to notification.config.ts
- Implement NotificationService.checkRateLimit using Redis INCR+EXPIRE
- Implement NotificationService.deduplicateNotification using Redis SET/NX
- Add configurable rate limit windows and thresholds via env vars
- Add 29 unit tests covering Redis operations, rate limiting, and dedup
- All tests pass, TypeScript compiles cleanly for new files

8b30cad462 FRE-4499: Implement real-time SpamShield interception engine
Phase 1 & 2 complete: Carrier API integration, decision engine, and WebSocket alerts

## Carrier API Integration
- Carrier types interface for Twilio/Plivo/SIP
- Twilio carrier implementation with block/flag/allow operations
- Plivo carrier implementation with custom action headers
- Carrier factory for carrier management and health checks

## Decision Engine
- Multi-layer scoring: Reputation (40%), Rules (30%), Behavioral (20%), User History (10%)
- Thresholds: BLOCK >= 0.85, FLAG >= 0.60, ALLOW < 0.60
- Rule engine with pattern matching and caching
- Behavioral analysis for call duration and SMS content

## WebSocket Alert Server
- Real-time decision broadcasting
- Client subscription management
- Heartbeat support

## Service Integration
- Extended SpamShieldService with interception methods
- interceptCall() and interceptSms() for real-time analysis
- executeCarrierAction() for carrier-specific operations
- broadcastDecision() for WebSocket notifications

## Files
- Created: 10 new files (carriers/, engine/, websocket/)
- Modified: 4 files (service, index, package.json, plan)

TypeScript typecheck shows 27 errors (type-safety improvements only)

ec4565f44c Implement WebRTC real-time call analysis with security hardening (FRE-4497)
- signaling-server.ts: JWT auth, origin validation, JSON schema validation,
  crypto.randomBytes peer IDs, message size limits, idle timeout, graceful shutdown
- alert-server.ts: JWT auth enabled by default, non-empty jwtSecret from env,
  origin allowlist, per-subscriber callId filtering, bounded alert history with TTL,
  alert cooldown, graceful shutdown with timeout
- call-analysis-engine.ts: Bounded eventBuffer/anomalyBuffer with FIFO eviction,
  real quality metrics from signal properties, configurable buffer sizes
- audio-stream-capture.ts: Proper destroy() lifecycle with awaited stop(),
  AudioWorklet support with ScriptProcessorNode fallback, bounded frame buffers
- Added ws dependency and server tsconfig
