chore(deps): update anyio requirement from <4.6.1,>=4.4.0 to >=4.4.0,<4.9.1

[dependabot]

Updates the requirements on anyio to permit the latest version.

Release notes

Sourced from anyio's releases.

4.9.0

• Added 4 new fixtures for the AnyIO pytest plugin:
  • free_tcp_port_factory: session scoped fixture returning a callable that generates unused TCP port numbers
  • free_udp_port_factory: session scoped fixture returning a callable that generates unused UDP port numbers
  • free_tcp_port: function scoped fixture that invokes the free_tcp_port_factory fixture to generate a free TCP port number
  • free_udp_port: function scoped fixture that invokes the free_udp_port_factory fixture to generate a free UDP port number
• Added stdin argument to anyio.run_process() akin to what anyio.open_process(), asyncio.create_subprocess_…(), trio.run_process(), and subprocess.run() already accept (PR by @​jmehnle)
• Added the info property to anyio.Path on Python 3.14
• Changed anyio.getaddrinfo() to ignore (invalid) IPv6 name resolution results when IPv6 support is disabled in Python
• Changed EndOfStream raised from MemoryObjectReceiveStream.receive() to leave out the AttributeError from the exception chain which was merely an implementation detail and caused some confusion
• Fixed traceback formatting growing quadratically with level of TaskGroup nesting on asyncio due to exception chaining when raising ExceptionGroups in TaskGroup.__aexit__ (#863; PR by @​tapetersen)
• Fixed anyio.Path.iterdir() making a blocking call in Python 3.13 (#873; PR by @​cbornet and @​agronholm)
• Fixed connect_tcp() producing cyclic references in tracebacks when raising exceptions (#809; PR by @​graingert)
• Fixed anyio.to_thread.run_sync() needlessly holding on to references of the context, function, arguments and others until the next work item on asyncio (PR by @​Wankupi)

• Fixed anyio.Path.iterdir() making a blocking call in Python 3.13 ([#873](https://github.com/agronholm/anyio/issues/873) <https://github.com/agronholm/anyio/issues/873>_; PR by @​cbornet and @​agronholm)

• Fixed anyio.to_thread.run_sync() needlessly holding on to references of the context, function, arguments and others until the next work item on asyncio (PR by @​Wankupi)

4.8.0

• Added experimental support for running functions in subinterpreters on Python 3.13 and later
• Added support for the copy(), copy_into(), move() and move_into() methods in anyio.Path, available in Python 3.14
• Changed TaskGroup on asyncio to always spawn tasks non-eagerly, even if using a task factory created via asyncio.create_eager_task_factory(), to preserve expected Trio-like task scheduling semantics (PR by @​agronholm and @​graingert)
• Configure SO_RCVBUF, SO_SNDBUF and TCP_NODELAY on the selector thread waker socket pair (this should improve the performance of wait_readable())
