Swap reusable task queues, borrow the polling waker, and process queued wakes as ordered contiguous slices. Preserve wake accounting, metrics, and shutdown ownership. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> Copilot-Session: 1803d5f8-45cd-4fa3-a31a-de048ca6d289

Consolidates the executor benchmarks into 23 shared metabench scenarios and reduces runtime overhead with reusable queue swaps, borrowed polling wakers, and ordered wake-slice processing.
Three-run Linux Gungraun medians show 7.25% fewer instructions for one spawn/complete, 8.72% for a 10,000-task ready burst, 9.23% for 32 awakened tasks, and 13.31% for overflow processing. All 21 steady-state scenarios remain allocation-free. Public APIs, scheduling boundaries, wake accounting, metrics, and shutdown lifetime contracts are preserved.
The before/after report includes every scenario, raw repeated counts, toolchain and reproduction commands, timing observations, rejected candidates, and the stopping rationale. This establishes measured local improvements, not global optimality.
Independent Opus, Sonnet, and GPT reviews found no blocking issues. Required automation is green for this revision, and Codecov reports all modified coverable lines covered. The PR remains a draft.
