Subject: [PATCH] feat(identity): add migration script for Ollama/Python config

- Auto-detects Python command, platform, architecture
- Probes Ollama (local vs remote)
- Sets prose_model based on machine (qwen3:8b for GURU-5070, else qwen3:14b)
- Tested on Mikes-MacBook-Air: all fields populated correctly

Ready for coord rollout to all machines.
