Surface "Require lockfile" policy failures directly in the PR checks summary #246

With the Require lockfile policy enabled, policy failures are difficult to discover. The PR shows required checks as “Expected — Waiting for status to be reported,” suggesting CI hasn’t started rather than that execution is blocked.

To find the reason, users have to open Checks, select the affected workflow, and find the error under Annotations, below an empty workflow graph.

Are there plans to surface the policy failure and remediation directly in the PR checks summary?
