1. Add logger to writeCacheFile (version-cache.ts)
- Now logs warnings when file write fails
- Helps debugging in production environments
2. Sanitize logging in parseGroupResult (communities.ts)
- Changed from info to debug level
- Removed full node/groupNode dumps (sensitive data)
- Now only logs nodeTag and groupId
3. Add input validation in parseNewsletterCreateResponse (newsletter.ts)
- Validates response structure before destructuring
- Adds fallback values for parseInt (prevents NaN)
- Adds null checks for optional fields
4. Add health-status.ts module
- getHealthStatus(): Full health check with circuit breakers, cache, memory
- isHealthy(): Simple boolean for liveness probes
- getSimpleHealthStatus(): Returns 'ok', 'degraded', or 'error'
- Useful for k8s probes and monitoring dashboards
