Add comprehensive structured logging system, then stop development:
- Create Logger module with JSON output and configurable log levels
- Implement hash-based request ID generation for request tracing
- Add performance timing and client IP detection to HTTP server
- Enhance startup logging with module loading and configuration checks
STOPPED: Feature violates Low-Tech principles
- 200+ lines logging vs 100 lines business logic (code bloat)
- JSON serialization overhead reduces performance
- No current production need for structured monitoring
- Simple print() statements sufficient for current scale
Branch parked for future consideration when monitoring requirements
actually emerge. Issue #54 deferred to v0.2.x milestone.
