host-persist: durable storage adapter for persist/* ops + acceptance
Sx_persist_store services every persist/* IO op against on-disk storage
(append-only log + separate monotonic .seq high-water + per-key kv files,
SX-serialized). Wired into the (eval) suspension loop, cek_run_with_io
bridge, and in-process _cek_io_resolver. Data-loss repro now (3 3 3).
New persist_durable_test.sh: durable + monotonic-seq + streams + kv +
real process restart all green (5/5).

# Acceptance test for the host durable-storage adapter (Sx_persist_store).
#
# Exercises `persist/durable-backend` (REAL `perform`, not the mock) under the
# WORKTREE-built sx_server.exe, and asserts:
# 1. durable: writes land on disk and read back (the silent-data-loss repro
# from plans/persist-on-sx.md now returns correct values).
# 2. last-seq is monotonic across truncate (compaction never reassigns a seq).
# 3. kv ops round-trip and delete.
# 4. recovery: a REAL process restart (write, exit, fresh process, replay)
# recovers state from disk.
#
# Run from repo root or anywhere; locates the worktree binary relative to itself.
