Updates only the provided fields of an existing component item (epic, feature, task) in a project. The description and internalNote fields accept HTML or Markdown and will be converted to the internal format. When the conditions array is provided, it completely replaces existing conditions. Conditions with id are updated, conditions without id are created, and conditions not in the array are deleted. Updating an item triggers automatic side effects including condition recalculation, project configuration change tracking, and timeframe updates.
