Defines how rayon CPU-parallel workers compose with single-thread async io_uring instances. Recommends one ring per session (model B) with the SQPOLL kernel thread as dispatcher when available. Locks in non-blocking submission, registered-buffer ownership rules, local-queue backpressure, and a per-submit fallback chain to pread64/pwrite64. Wire-compat invariants confirmed unchanged. Tracking: #1283. Implementation follow-up: #1284.
