workflow-engineer-fix-slicelisted

# workflow-engineer-fix-slice Address slice-review findings on a single slice. Dispatched after the slice review (the `runReviewSlice()` fan-out in `implement-slice`) returns a BLOCK verdict. Scope is read from the most recent slice-review comment on the slice (newer than the slice branch's last `Refs #<slice#>` commit), with user directives in the same window overriding. In the new model, E2E passing is a separate earlier phase (`workflow-engineer-diagnose-e2e` + `workflow-engineer-fix-e2e`); this fix loop only addresses the reviewer's findings. The calling workflow re-runs the slice review after the fix — this skill does no re-validation and flips no labels. ## When to activate Activate this skill whenever: - The dispatch prompt opens with `Fix the review feedback on slice #<n>`. - The user types `/workflow-engineer-fix-slice`, or phrases like "fix slice #<n> per the reviewer findings". Do NOT activate to pass E2E acceptance (use `workflow-engineer-diagnose-e2e` / `workflow-engineer-fix-e2e`), to fix a PR (use `workflow-engineer-fix-pr`), or to implement fresh tasks (use `workflow-engineer-implement-task`). ## Input contract Read the slice issue #<n> body. Locate the task block(s) in the `## Tasks` checklist (each entry is a header `[ ] \`<id>\` · **<type>** · blocked-by <ids|—>`, the delivery on the next line, a `covers:` + `contract:`/`entry-source:`/`done:` pointer line, then `scenario:` and a fenced ```gherkin block of named Scenarios). The checklist is the dura
