SRE-715: Add PR-title preflight workflow + bump SHA pins

[TimDiekmann]

Summary

• Wires the new reusable preflight-pr-title.yml workflow into this repo's preflight chain.
• Bumps every hashintel/.github reusable-workflow SHA pin (preflight + housekeeping) to e12e306 in one atomic change — Renovate would have done the bump on its next pass; doing it here keeps the change reviewable as a single PR.

The new check enforces that human-authored PR titles include a Linear issue ID (e.g. H-1234, BE-5678) in the prefix segment. Bot-authored PRs (hash-worker[bot], dependabot[bot], …) are skipped automatically.

Related: SRE-715, follow-up of the source change in hashintel/.github#65 (H-6402 was the original rollout of the preflight chain).

Test plan

• Preflight PR title job runs and passes on this PR (title contains SRE-715)
• Other preflight jobs (stale-approvals, dependencies, todo-comments) still pass after the SHA bump
• Housekeeping workflow continues to function with the new pin

PR Summary

Low Risk
Low risk: changes are limited to GitHub Actions workflow wiring and SHA pin bumps, with no impact to application runtime behavior. Main risk is CI behavior changes (new PR-title gate or upstream reusable-workflow changes) affecting PR validation.

Overview
Adds a new pr-title job to the Preflight workflow by wiring in the reusable preflight-pr-title.yml workflow, introducing an additional PR validation gate.

Updates SHA pins for the hashintel/.github reusable workflows used by both preflight.yml and housekeeping.yml to e12e306… (stale approvals, dependencies, todo comments, and housekeeping dependencies).
