AioKV: async file-backed key-value store for single-process local state
(persist-forever, not a cache — no TTL/eviction). atomic writes via
temp-file + os.replace, every read and write under one asyncio.Lock,
blocking fs calls off the loop via asyncio.to_thread. set(key) defaults
to int(time.time()) for seen/did-X-at-T. aiocache alias kept for
back-compat. src/ layout, hatchling, aiofiles dep.
