Todo List Management Tools

Added comprehensive todo list functionality with two new tools:

TodoWrite - Update and manage your task list during coding sessions

• Create, update, and track todos with status (pending, in_progress, completed) and priority (high, medium, low)
• Automatic progress tracking with visual indicators
• Use it to organize complex multi-step tasks and maintain focus

TodoRead - View your current todo list

• Quickly check pending tasks and current progress
• Shows focused view by default, with verbose option for full list
• Helps maintain context across long coding sessions

# Claude will proactively use these tools to track progress
# You can also explicitly ask to see or update the todo list
"Show me my todo list"
"Add a todo to implement dark mode"
