add "local network access" permission for macOS 15 runners

[glyph]

Description

Attempting to test multicast sockets results in routing errors, which suggests that the code is running without "local network access" permissions.

Ideally this would be configurable, so that code could be tested to ensure that it doesn't need this permission, but when it is necessary for a certain function it would be nice to have.

Is it regression?

sort of? it regressed from macos 14

Expected behavior

I would expect to be able to test multicast sockets

Actual behavior

Multicast sockets give a "no route to host" error when sending

Repro steps

1. bind a multicast socket
2. send some data to it

Hi @glyph
Apple introduced new LNP policy with macOS Sequoia which is not controlled by TCC or MDM. We are working on resolving this. For more information see there: thread , thread
