Upgrade to interprocess 2.0.0 (#12729)
# Description This fixes #12724. NetBSD confirmed to work with this change. The update also behaves a bit better in some ways - it automatically unlinks and reclaims sockets on Unix, and doesn't try to flush/sync the socket on Windows, so I was able to remove that platform-specific logic. They also have a way to split the socket so I could just use one socket now, but I haven't tried to do that yet. That would be more of a breaking change but I think it's more straightforward. # User-Facing Changes - Hopefully more platforms work # Tests + Formatting - 🟢 `toolkit fmt` - 🟢 `toolkit clippy` - 🟢 `toolkit test` - 🟢 `toolkit test stdlib`
