fix: apply fork detection to SSH/remote path in git:get-check-runs

The remote (SSH) code path was still using the hardcoded
repos/{owner}/{repo} pattern, causing CI checks to fail for fork
projects on SSH workspaces. Apply the same fork detection logic:
detect parent repo via gh repo view, find the PR by branch name with
owner filtering, then use the parent repo for gh pr checks and the
gh api check-runs call.
