PR Summary

Low Risk
Only reusable-workflow pin updates with no application or runtime code changes; CI behavior may shift only if the upstream hashintel/.github commit changed those workflows.

Overview
Renovate bumps the pinned commit for shared hashintel/.github reusable workflows from 8c1a3b1 to b7a5d7f across housekeeping and preflight CI.

Housekeeping (housekeeping-dependencies.yml) and preflight jobs (preflight-dependencies, preflight-pr-title, preflight-todo-comments) now call the updated digest; workflow inputs, permissions, and secrets in this repo are unchanged.
