[4.0.0] - Unreleased

Target framework changed from netstandard2.0 to net10.0
ImpromptuInterface removed — replaced by source-generated proxies and opt-in DispatchProxy fallback
Proxy creation now requires [SignalARRRContract] attribute on interfaces (or reference Cocoar.SignalARRR.DynamicProxy for runtime fallback)
Custom IAuthenticator interface removed — use ASP.NET Core authentication handlers and [Authorize] policies instead
HTTP Proxy pass-through feature removed (deferred to Phase 2)
netstandard2.0 target dropped — all packages now target net10.0 (except SourceGenerator which targets netstandard2.0 per Roslyn requirements)
Hub-level [Authorize] inheritance restored: if the Hub class has [Authorize], ServerMethods classes inherit it automatically (behavior change from v2.x where this was disabled)

Source Generator: Compile-time proxy generation from [SignalARRRContract] interfaces — zero reflection, AOT-friendly
Cocoar.SignalARRR.Contracts: Single-reference meta-package for shared interface projects (attribute + generator + ProxyGenerator)
Cocoar.SignalARRR.DynamicProxy: Opt-in DispatchProxy-based runtime fallback for plugin/dynamic scenarios
CancellationToken server-to-client propagation: Server can pass CancellationToken to client methods and cancel remotely
ServerProxyCreatorHelper.StreamAsync<T>: Server can request IAsyncEnumerable<T> streams from client methods
ServerStreamManager: Channel-based stream correlation for server-initiated client streams
StreamItemToServer / StreamCompleteToServer hub methods for client-to-server stream item delivery
ClientManager typed extensions: GetTypedMethods<T>(connectionId) for server-to-client RPC from outside hub context
Authorization integration tests: Tests for authenticated calls, unauthenticated rejection, and hub-level auth inheritance
TreatWarningsAsErrors: Enabled globally via Directory.Build.props
