What

Add CodSpeed benchmarks for ZeroconfIPv4Address / ZeroconfIPv6Address construction and hashing.

Why

get_ip_address_object_from_record builds one of these objects per A/AAAA record on a cache miss, and the objects are hashed when stored in sets/dicts. There is currently no benchmark guarding the construction or hash cost of this hot path, so regressions (or improvements) go unmeasured.

This establishes the baseline before a follow-up that reworks how the per-instance hash is cached.

How

Four benchmarks under tests/benchmarks/test_ipaddress.py:

construct 1000 distinct IPv4 / IPv6 address objects (__init__ cost)
hash a warm IPv4 / IPv6 address 1000× (memoized-hash cost)

Testing

SKIP_CYTHON=1 poetry run pytest tests/benchmarks/test_ipaddress.py -v — 4 passed. ruff + ruff-format clean.
