refactor: full agent system revision — migrate to GLM-5.1, fix delegation chains, audit consistency

- Migrate 8 agents from openrouter/qwen3.6-plus:free to ollama-cloud/glm-5.1
- Assign thinking/variant/instant depth by role complexity
- Fix broken delegation chains: system-analyst, all developer agents, devops-engineer now can reach orchestrator
- Add task permissions to browser-automation, visual-tester, capability-analyst, markdown-validator
- Add visual-tester permission to flutter-developer and frontend-developer
- Fix capability-index.yaml routing map indentation (go_* keys misplaced)
- Add delegates_to and variant fields to capability-index.yaml
- Update KILO_SPEC.md agent table with Variant column
- Update AGENTS.md with Model/Variant/CanCall columns
- Update kilo.jsonc ask agent model
- Fix YAML indentation in capability-analyst.md and markdown-validator.md
- Update agent-architect.md template models (remove gpt-oss, qwen3.6-plus)
- Add Skills Reference tables to 7 previously unlinked agents
- Full audit: 10/10 consistency checks passed
