Registers an async after-each test hook.

# =============================================================================
# async_teardown — Registers an async after-each test hook.
# =============================================================================
#
# What this teaches:
#   • Async test hooks — `async_teardown` registers an async cleanup hook that runs after each test case.
#   • Async counterpart — Pairs with `async_setup` (async before-each) and mirrors `teardown` (sync after-each).
#
# Common mistakes:
#   • Confusing `async_teardown` (async teardown) with `async_setup` (async setup) — they run at opposite ends of each test.
#
# See also: teardown, async_setup
