Callable posture for asynchronous stream functions.

# =============================================================================
# 异流 — Asynchronous stream callable posture
# =============================================================================
#
# What this teaches:
#   • Async stream posture: `异流 → T` yields promised pulls of `T`.
#   • Yield with `让出`; consume the stream with `遍历 取自` inside an async body.
#
# Common mistakes:
#   • Expecting every backend to lower `异流` — some fail closed until a
#     channel/async-cursor carrier lands.
#
# See also: 流, 异步, 让出
# =============================================================================

# GRAMMAR:
#   callablePosture :← '异流'
#
# BACKEND:
#   Product path is Rust async-cursor; other backends may fail closed.
