Converge the Io unification (PLAN-IO-UNIFY Phase 5). The bespoke fiber-task layer in sched.sx — Task / TaskState / TaskErr / go / wait / cancel(Task), plus Scheduler.task_allocs and its deinit bookkeeping (~130 lines) — is removed. There is now ONE async stack: context.io.async / await / cancel / race / sleep over the Io protocol, with the Scheduler as the fiber Io's engine + driver (spawn / yield_now / suspend_self / wake / run / block_on_fd remain as the raw primitives; race stays in sched.sx because it needs meta.sx's make_enum/make_variant). Migrated the four go/wait users to context.io: - 1813 — interleave + cancel (sequence 1 2 3 42 100 -99) - 1817 — m1 end-to-end (completion in deadline order, sum 123) - 1819 — double-AWAIT loud-abort via the Future one-awaiter guard - 1820 — deinit: dropped the go/task_allocs tasks; now exercises timers/io_waiters/ kq cleanup (freed=2, live=3 = the documented per-spawn closure-env residual) Updated readme.md (the user-facing async section documents context.io.async / await / race / sleep) and the stale sched.go/sched.Task comments in io.sx. Suite 854/0; no .ir churn (Task removal touched no snapshotted IR); migrated examples byte-identical on aarch64-macOS + aarch64-linux. PLAN-IO-UNIFY Phases 0-5 all complete — the two parallel async stacks are now one, behind context.io.
