Add reviewed primary-content task scope revision

Adds the opt-in primary-content-20261103 task scope revision supporting https://github.com/lexmount/browser-eval/pull/131.

The review examined 91 suite-qualified tasks with saved failures for all 11 methods. Exactly 64 tasks change relative to review-550-20261023; 27 retain their requirements. The rationale file lists each change and retention reason. Results identified candidates for inspection; task purpose and independent page evidence determined the revised requirements. This is a disclosed post-outcome scope review.

Original frozen inputs, the default 550-task catalog, existing revisions and release tags remain unchanged. The 530-task report is a subset, not a dataset deletion. The cumulative revision preserves prior corrections. No provider responses, measured scores, credentials or captured pages are included.

Validation: all 550 tasks pass the maintained input checks; exactly 64 prompt/acceptance changes against the predecessor; parent hashes and review controls verified. The archive and manifest were rebuilt with the maintained publication builder.

This is a PR for review only. It does not merge changes, create a release tag or update Browser Eval to an unmerged dataset ref.

The active population is recorded in `manifest.json` under `edition`; retained historical definitions do not increase that population.

+# Primary-content scope revision
+
+This opt-in `task_scope_revision` preserves `review-550-20261023` and changes
+exactly 64 tasks relative to that predecessor. The original 550-task catalog,
+source files, existing revisions and release tags remain unchanged. The 530-task
+report selects a subset of this catalog; this revision does not delete its
+20 supplemental examples.
+
+The review examined 91 suite-qualified tasks with saved failures for all 11
+methods. Results selected candidates for inspection; task purpose and independent
+page evidence determined which requirements to remove. This is a post-outcome
+scope review, not a blind evaluation. A missing call was not counted as failure.
+
+The 64 changes remove specifically reviewed interface requirements and update
+the task wording accordingly. They retain each task's existing title, attribution,
+body, list records and displayed-comment requirements. They do not remove all
+navigation or all controls across the dataset. The other 27 reviewed tasks retain
+their requirements because they identify the requested content or their removal
+lacks sufficient support. See `primary-content-20261103-rationale.json` for every
+changed rule, per-task reason and retained case.
+
+`primary-content-20261103.json` is cumulative so the existing export command can
+apply it directly to the frozen parent. Its additional entries preserve previous
+corrections; they are not new changes in this review. `reviews.json` binds the
+complete field differences, source hashes and executable controls. Independently
+captured page files remain external approved inputs; this dataset contains their
+bindings, not captured pages, provider responses or measured scores.
+
+Use Browser Eval's revision inspector and export command with
+`--revision primary-content-20261103`. The supporting code is reviewed separately
+in https://github.com/lexmount/browser-eval/pull/131. Export requires the original
+frozen inputs and the declared review inputs; it fails on missing or altered
+bindings. Inspect the revision before applying it to saved evidence. Compare
+methods only after applying the same revised requirements to their saved outputs;
+retain original verdicts and identify the new task contract. Do not relabel old
+results as unchanged-task measurements.
+
+This PR proposes an opt-in revision, not a new certified edition. Dataset release
+approval and tagging are separate. Browser Eval's data lock can select the reviewed
+HF commit after it is merged; it must not pin an unmerged PR ref.
