When a merge-train branch merges and is recreated, add the ci-wakeup-pr-after-merge label to all PRs that have passed CI and have automerge enabled. This triggers a CI re-run (no-op via cache) so those PRs can proceed through the merge queue. The label is removed immediately by ci3.yml so it can be re-applied next time.

Cherry-picks merge-train skills from b453bd4, updates the merge-train-infra skill with the new wakeup-prs feature, and rewrites the merge-train readme to point to the skills as LLM-consumable documentation.

Currently, there is an edge case where auto-merge PRs are stuck if a merge-train PR has been queued for merge. The branch becomes protected, and github never reconsiders the PR for automerge.
Now:
