Outcome

A task's status, body, or metadata is updated in the configured backend. Progress notes are appended without overwriting existing content. When completing a task, a resolution (Summary of Changes or Reasons for Scrapping) is written to the task body before marking done.

Acceptance Criteria

• Specified fields are updated in backend
• Existing body content is preserved; new content is appended
• Completed tasks have a "Summary of Changes" or "Reasons for Scrapping" section in body
• User confirms before task is marked as completed or scrapped

Constraints

• Read tasks.backend from .groove/index.md to determine backend
• If tasks.backend: none, no-op with friendly message
• Never mark a task completed without a resolution section in the body
• Ask user to provide resolution if task body has none
