5.3.0
(feat): Add aiohttp auto-detection for async clients. When the httpx-aiohttp package is installed,
the async client automatically uses HttpxAiohttpClient instead of the default httpx.AsyncClient.
Adds optional aiohttp and httpx-aiohttp dependencies exposed via a [aiohttp] pip extra,
along with DefaultAioHttpClient and DefaultAsyncHttpxClient convenience classes in _default_clients.py.
5.2.2
(fix): Fix extra_dependencies override behavior so user-specified dependency
versions reliably take precedence over bundled generator defaults.
Previously, bundled dependencies (e.g., pydantic, typing_extensions) added
during generation would overwrite customer version pins from
extra_dependencies. User overrides are now protected from being
overwritten by internal dependency additions.
