[Feature Request] Single Agent mode_Todo List Enhancement

[Pakchoioioi]

Toolkit: TodoToolkit

Current State
The current TodoToolkit only provides a single method: todo_write().

Required Enhancement
To align with competitive structured task management systems, we need to extend TodoToolkit with the following capabilities:

• task_create
• task_get
• task_update
• task_list

Functional Requirements

• Support full task CRUD operations
• Support task state transitions:
  • pending → in_progress → completed
• Support task dependencies:
  • blocks
  • blockedBy

Frontend Requirement (Single Agent Mode)
In single-agent mode, the frontend should use TodoToolkit as the primary task display source.

Reason:

• It provides structured JSON output (.todo.json)
• Can be directly parsed and rendered by frontend in different CRUD operations

Example Output Format:

[
  {
    "content": "xxx01",
    "active_form": "Reading code",
    "status": "completed"
  },
  {
    "content": "xxx02",
    "active_form": "Modifying auth",
    "status": "in_progress"
  },
  {
    "content": "xxx03",
    "active_form": "Running tests",
    "status": "pending"
  }
]
