PR Summary

Low Risk
CI-only digest pin updates for shared housekeeping/preflight workflows; no application or runtime behavior changes in this repo.

Overview
Pins all reusable workflow references in hashintel/.github from digest b52c157 to a438cfc on the main ref.

housekeeping.yml: the renovate job’s housekeeping-dependencies.yml call is updated.

preflight.yml: the same digest bump applies to preflight-dependencies.yml, preflight-todo-comments.yml, and preflight-pr-title.yml.

No workflow inputs, permissions, or triggers change—only which commit of the shared actions repo is used.
