feat(open-pr-board): approve waiting fork workflow runs

+- **Approve and run checks** — cards identify fork workflow runs awaiting execution
+  approval. Open **Checks**, inspect the linked workflow and contributor code, then
+  explicitly confirm **Approve and run checks** for a specific run, attempt, and
+  commit. This uses GitHub's fork workflow approval endpoint, not a PR approving
+  review, re-run, auto-merge, or required-check bypass. The board refreshes after
+  success and records workflow execution approval in history without changing the
+  PR's triage bucket, review queue, or staged feedback. Execution events do not
+  calibrate AI review strictness.
+  `ACTION_REQUIRED` checks are shown as needing attention, not test failures:
+  submission gates can require PR reviews rather than execution approval.
+  Queued/running checks, actual failures, deployment/environment approvals, private
+  forks, and non-fork runs are not eligible. Only the latest run for each workflow
+  associated with this PR at the current fork head is offered; runs associated only
+  with another PR do not displace it. Discovery errors remain visible as a fixed
+  failure indicator, without retaining raw tool errors; refresh to retry.
+  Unassociated fork runs are matched by repository IDs, branch, and exact SHA.
+  The authenticated `gh` account needs repository write access and token access to
+  Actions; GitHub enforces final eligibility and permissions. Errors are surfaced,
+  never automatically retried. After an unconfirmed write, inspect the run on GitHub
+  before retrying. Run state and PR head are checked again immediately before the
+  write, but GitHub's approval API provides no atomic SHA/attempt precondition.
 - **GitHub actions** — submit feedback, request changes, close a PR, or approve it and
   enable auto-merge with a merge commit. Each action needs two clicks to confirm and
   is also recorded in local board history. Approval is pinned to the board's commit
