Turn ServiceNow article feedback into one task to fix it

**Objective:** Collect the unresolved negative feedback on article `{article-number}` into one feedback task for `{assignment-group}`.

**Step 1: Read the article**

Call `servicenow-get-knowledge` with number `{article-number}`. Keep sys-id, short-description, author, workflow and rating.

**Step 2: Gather the feedback**

Call `servicenow-get-knowledge-feedback` with article `{article-number}`. Keep entries where resolved is false and either flagged is true, useful is No, or rating is 2 or lower. Keep each entry's sys-id, rating, reason and comments.

**Step 3: Avoid a duplicate task**

Call `servicenow-get-knowledge-feedback-task` and keep tasks whose article is `{article-number}` and whose state is Open or Work in Progress. If one exists, show it and stop.

**Step 4: Confirm**

Summarize the feedback themes in two or three bullets. Propose the task: short-description "Review feedback on `{article-number}`: <main theme>", description listing each feedback entry's rating, reason and comments, assignment-group `{assignment-group}`, type Flag article if any entry is flagged and Rating otherwise, feedback set to the sys-id of the most serious entry. Also propose marking every entry in the list as resolved. Ask for an explicit yes.

**Step 5: Write**

1. Call `servicenow-add-knowledge-feedback-task` once with the confirmed values.
2. For each feedback entry in the list, call `servicenow-update-knowledge-feedback` once with its sys-id, resolved true and work-notes "Captured in a feedback task for `{assignment-group}`."

**Step 6: Verify**

Call `servicenow-get-knowledge-feedback-task` and find the new task for `{article-number}`. Report its number and how many feedback entries were marked resolved.

**Rules & Guidelines:**

* Write tools allowed: `servicenow-add-knowledge-feedback-task` once and `servicenow-update-knowledge-feedback` once per listed entry, after one confirmation. Do not call `servicenow-update-knowledge` to edit the article itself.
* If the task add fails, do not mark any feedback resolved.

**Validation:**

* If there is no unresolved negative feedback, say so and stop.
