Attaches a description string to CLI metadata.

# =============================================================================
# 描述 — Attaches a description string to CLI metadata.
# =============================================================================
#
# What this teaches:
#   • CLI metadata — `@ 描述 <string>` attaches a human-readable description to a CLI command's metadata.
#   • Annotation syntax — used together with `@ cli` to annotate entry points with metadata for CLI generation.
#
# Common mistakes:
#   • Using 描述 without a corresponding @cli annotation — `@ 描述` only has meaning when attached to a `@ cli` entry point.

# =============================================================================

# 描述 — CLI description annotation
#
# GRAMMAR:
#   annotation :← '@' '描述' stringLit
#
# EXPECTED OUTPUT:
#   No 入口 — declaration or test-runner surface only.
#
# BACKEND:
#   declaration-only CLI metadata (whitelist: 描述/descriptio.fab).
