Resolve ServiceNow problems only when every task is done

**Objective:** Resolve problem `{problem-number}` with fix notes `{fix-notes}`, but only if nothing is left open under it.

**Step 1: Read the problem and tasks**

* Call `servicenow-get-problem` with number `{problem-number}`. Keep sys-id, state, known-error and cause notes context. If already Resolved or Closed, stop.
* Call `servicenow-get-problem-task` with problem `{problem-number}`.

**Step 2: Gate**

If any problem task is still open, list them and stop: the problem cannot be resolved while work is outstanding. Offer the user the choice of finishing those tasks first.

**Step 3: Confirm**

List the resolution-code values the tool accepts and propose the one that fits (for example Fix applied). Show the problem, current state, new state Resolved, the resolution code and `{fix-notes}`. Ask for an explicit yes.

**Step 4: Write once**

Call `servicenow-update-problem` once with sys-id, state Resolved, resolution-code, fix-notes `{fix-notes}` and work-notes "Resolved: `{fix-notes}`".

**Step 5: Verify and follow up**

Re-read with `servicenow-get-problem`. If known-error was true, call `servicenow-get-knowledge` with short-description.contains set to key words from the problem and remind the user that any known-error article should be updated or retired.

**Rules & Guidelines:**

* The only write tool this prompt may call is `servicenow-update-problem`, once, after confirmation. Do not call `servicenow-update-problem-task`, `servicenow-update-knowledge` or `servicenow-update-incident`.

**Validation:**

* If `{problem-number}` is not found, stop.
