Feature Request: Per-Mode and Per-Agent LLM Routing

Feature Description

Mode-Specific Model Routing: Users can define a default model for each of Command Code's core operational modes.

• Planning Mode (planning): Maps to high-parameter, reasoning-heavy models (e.g., Deepseek V4 Pro, GLM 5.1) for complex architectural design, system breakdown, and step-by-step logic generation.
• Edit Mode (edit): Maps to fast, highly capable coding models optimized for syntax and refactoring to execute the plan quickly.
• Auto-Accept Mode (auto-accept): Maps to ultra-fast, low-latency models for rapid, low-risk changes (e.g., fixing linting errors, adding docstrings) where developer oversight is bypassed.
• YOLO Mode (yolo): Maps to high-context, highly capable models authorized to make sweeping, project-wide changes with deep contextual understanding.
• Custom Agent Model Binding: Users creating specialized, domain-specific agents within Command Code can lock a specific model to that agent.
• CLI Flag Overrides: The ability to temporarily override the default model for a specific session or command using a flag (e.g., command-code --plan --model deepseek-v4-pro).

Use Case

Explore-Plan-Execute Workflow

• Launching off multiple agents to explore legacy repo, each using lower cost and faster agents with big context windows
• Planning with SOTA OSS models with high reasoning capabilities
• Execute plans proposed by the Planning model using a cost effective model

Important for my workflow

首先跟踪 Command Code 当前如何为规划、编辑、auto-accept、YOLO 和自定义 agent 选择模型，然后检查 CLI 选项解析，以实现临时模型覆盖。完成的标准是：模式默认值、每个 agent 的绑定以及示例 --model 覆盖都能正常工作，且不会干扰 Explore-Plan-Execute 工作流。
