v0.2.0 — pure-code contract + platform dispatch

Breaking redesign of the request/result contract, plus platform dispatch and an iOS channel.

Changed (breaking)

• Pure-code string contract: Bridge.Request(int command, string payload, Action<int code, string data> onResult). INativeChannel = Send(long seed, int command, string payload) + event Action<long,int,string> OnResult. The framework never interprets code and never touches data — it just relays.
• Removed BridgeError/onError: errors are codes. Business owns 1/0/10086/…; the framework only mints RelayCode.Timeout/RelayCode.Disposed when it can't get a native result.

Added

• NativeChannelFactory.CreateForCurrentPlatform() — #if platform dispatch in one place (Editor/Windows → Mock, Android → JNI, iOS → P/Invoke), behind INativeChannel.
• AndroidChannel (JNI) + IosChannel (P/Invoke + GCHandle) C# sides; native contracts in docs/native-android.md, docs/native-ios.md (build the .aar / native lib on your side).

Verified

• dotnet 38 green; Unity 6: compile clean, EditMode 35/35, PlayMode 3/3 (main-thread dispatch, end-to-end timeout, 1000-request stress, steady-state zero-GC).
