[deep-report] Fix chat-ops.md example that does not use the steps.sanitized.outputs.text it describes

### Description
`docs/src/content/docs/patterns/chat-ops.md` (line 25) states that the ChatOps code-review example "references the triggering content via `steps.sanitized.outputs.text`", but the fenced example immediately below (lines 27-51) never actually uses that variable anywhere in its prompt body. A user copying the example verbatim won't find what the prose promised. Flagged and live-verified in the 2026-09-15 User Experience Analysis Report.

### Expected Impact
Restores trust/accuracy in a featured, frequently-linked pattern doc (cross-referenced from IssueOps/DispatchOps/LabelOps) so the example matches its own description.

### Suggested Fix
Add a line to the example's prompt body referencing `${{ steps.sanitized.outputs.text }}`, e.g. inserting `Triggering comment (sanitized): ${{ steps.sanitized.outputs.text }}` between the intro sentence and the "Examine the diff..." paragraph.

### Suggested Agent
Delight / docs-focused agent

### Estimated Effort
Quick (< 30 min)

Open docs/src/content/docs/patterns/chat-ops.md and inspect the description around line 25 and the fenced example on lines 27-51. Add the documented steps.sanitized.outputs.text reference to the prompt body, then verify the example matches the surrounding prose and renders correctly.
