ci: Add workflow to automatically retry failed jobs

.github/workflows/retry-failed-jobs.yaml

+
+# This workflow automatically retries failed jobs from other workflows to handle transient failures
+# such as:
+# - Runner acquisition timeouts ("The job was not acquired by Runner of type self-hosted even after
+#   multiple attempts")
+# - Self-hosted runners being temporarily unavailable due to maintenance or failures
+#
+# How it works:
+# 1. Triggers when a monitored workflow completes (success or failure)
+# 2. If the workflow failed on its first attempt, re-runs only the failed jobs
+# 3. Uses a GitHub-hosted runner to avoid the same runner acquisition issues
+#
+# To add retry support for another workflow, add its name to the `workflows` list below.
