<issue_title>[deep-report] Fix add_labels.cjs pagination bug — only first page of labels is fetched</issue_title>
<issue_description>### Description
The add_labels.cjs helper script only fetches the first page of labels from the GitHub API, silently ignoring any labels on page 2+. On repositories with more than 30 labels (the default page size), this means labels that exist in the repo cannot be applied by agents — either failing silently or erroring. This was reported as a community bug by @yskopets in issue #23914 (2026-03-31).

Expected Impact

Fixing the pagination will make label application reliable on all repositories regardless of label count, resolving silent failures for any agent that uses add_labels.cjs to apply labels from a large label set. This is a correctness bug affecting every automated labeling workflow.

Suggested Agent

A code-editing agent. The fix requires adding a pagination loop to the GitHub API call in add_labels.cjs — standard practice using the link header or by switching to octokit.paginate().

Estimated Effort

Quick (< 1 hour) — well-understood pagination pattern, single file change.
