TodoWrite Tool Schema Enhancement

What changed: TodoWrite tool now requires dual-form descriptions for all todo items Previous behavior: Todo items only had content and status fields:

{"content": "Fix authentication bug", "status": "pending"}

New behavior: Todo items require three fields including a new activeForm:

{
  "content": "Fix authentication bug",
  "activeForm": "Fixing authentication bug",
  "status": "pending"
}

Impact:

• Forces clearer articulation of both task goals and current actions
• Improves communication between AI and user about task progress
• Enables status spinner to show contextual progress messages (though todo lists remain hidden since v1.0.86)
• All three fields (content, activeForm, status) are now required for TodoWrite tool usage
• Note: While activeForm enhances the schema, users still cannot see todo lists due to display removal in v1.0.86
