Generic set collection type.

# =============================================================================
# copia — Generic set collection type
# =============================================================================
#
# What this teaches:
#   • Generic set collection type.
#   • Related keywords: lista, tabula, inter
#
# Common mistakes:
#   • Using `copia<T>` without an explicit type — `vacua` requires an explicit type annotation like `copia<numerus>` (SEM014).
#
# See also: lista, tabula, inter
# =============================================================================

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