Air 0.48.1

Air sites now respond correctly to HTTP HEAD requests. If you use Facebook link previews, Twitter cards, Slack unfurls, or uptime monitors that send HEAD, they work on Air out of the box.

What's fixed

• HTTP HEAD requests return 200 instead of 405. Every GET route (@app.page, @app.get, @router.page, @router.get) now responds to HEAD with the correct status, headers, and empty body. FastAPI's routing layer has never added HEAD to GET routes the way Starlette does. Air now restores that behavior in its own route class. (#1123)

• Cleaner linter config for dependency injection. Air's ruff.toml now lists its immutable function calls (Depends, Query, Header, etc.) in extend-immutable-calls, removing the need for noqa: B008 comments throughout the codebase. (#1109)
