Generic set collection type.

# =============================================================================
# 集合 — Generic set collection type
# =============================================================================
#
# What this teaches:
#   • Generic set collection type.
#   • Related keywords: 列表, 映射, ∈
#
# Common mistakes:
#   • Using `集合<T>` without an explicit type — `空集` requires an explicit type annotation like `集合<整数>` (SEM014).
#
# See also: 列表, 映射, ∈
# =============================================================================

# 集合<T> basic intrinsics
#
# Compiler-owned 集合<T> methodi — adde, habet, dele, longitudo, 空集.
#
# GRAMMAR:
#   copia.add(x) | copia.has(x) | copia.delete(x)
#   copia.length() | copia.is_empty()
#
# 集合<T> is a set-like collection; 空集 with 集合<T> creates an empty set.
#
# EXPECTED OUTPUT:
#   Smoke asserts exit 0 only.
#
# BACKEND: Go e2e whitelist — 集合 method surface not yet lowered for Go.
