feat: printing pod API + research completion events

Printing Pod:
- GET /api/state/printing_pod: check if ready, options available, cycles remaining
- POST /api/action/printing_pod_select {index}: select option 0/1/2

Research completion tracking:
- Automatic detection of newly completed techs on each state poll
- Events pushed to stream: 'research_complete' with unlocked buildings list
- Events pushed when Printing Pod becomes ready

Event daemon enhanced:
- Classifies 'research complete' events with actionable next steps
- Classifies 'printing pod' events with option viewing instructions

CLI: printing_pod, printing_pod_select <0|1|2>
