ranade-oss unblocks safer upstream updates for locked-down repositories

Some organisations restrict GitHub's built-in automation from opening pull requests, which can leave upstream synchronisation stalled after an update is merged. ranade-oss has extended an existing request signal so an external GitHub App can restart both the medium- and high-risk queues.

The important part is what did not change: the existing checks for classification, patch validation, review, draft status and merging still decide whether an update proceeds. The new bridge is deliberately narrow too: it can coordinate workflow runs and read the repository, but it cannot alter code, open or merge pull requests, deploy changes, or access secrets.
