Subject: [PATCH] Add client info case for DOTNET
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

ClientInfo.SDK has no value for .NET, so .NET clients — which already pass sdk=dotnet through livekit-ffi — land in UNKNOWN.
Replicating PR for ESP23 https://github.com/livekit/protocol/pull/1113/changes
Server-side parsing and Rust signalling support for the new value follow separately.
