Fix model config context/token limits and inject gutask orientation into agent identity

- Chat model max_tokens: 32000 → 4096 (was inflating context budget calculations)
- Utility model ctx_length: 8192 → 14000 (matches GLM flash actual loaded context)
- Utility model max_tokens: explicit 2048 cap (utility tasks need short responses)
- Utility model name: full zai-org/glm-4.7-flash to target correct LM Studio instance
- pull-agent-identity.py: include agent_id and gutask orientation block in system prompt
- gutask.md: expand lore command docs, note done auto-creates review record
