Release v5.1.0

Changes since v5.0.0:
- Fix multicast stream bug allowing multiple subscribers to receive updates
- Add MulticastStream class for broadcasting to multiple AsyncStream consumers
- Use Swift 6 isolated deinit for safe cleanup in SharedState
- Rename types to WCSession prefix convention (breaking change):
  - SessionProviding → WCSessionProviding
  - PreviewSession → PreviewWCSession
  - MockSession → MockWCSession
  - FlakySession → FlakyWCSession
- Add comprehensive unit tests for multicast behavior
- Add E2E tests for bidirectional communication (watchOS → iOS)
- Add E2E tests for multiple SharedState multicast
- Update all documentation to reflect v5.0.0 API changes
- Remove outdated references to versioning, rate-limiting, and removed types

Release v5.0.0: Complete rewrite with Swift 6 concurrency

This is a complete rewrite of WatchConnectivitySwift with a modern API designed
for Swift 6 strict concurrency and async/await patterns.

## New Features

- **Type-safe request/response**: `WatchRequest` protocol with associated `Response` type
- **Handler registration**: Register handlers with closures instead of subclassing
- **SharedState<T>**: Automatic state synchronization via `applicationContext` using @observable
- **File transfers**: Full support with progress tracking and async/await
- **Retry policies**: Built-in `.default`, `.patient`, `.none` with fixed 200ms delay
- **Delivery strategies**: Fallback mechanisms (message → userInfo → context)
- **Session health monitoring**: Track connection health with recovery suggestions
- **Diagnostic events**: AsyncStream for debugging connectivity issues
- **E2E test infrastructure**: Paired iOS/watchOS simulator testing

## Breaking Changes from v1.0.0

- Main class renamed from `WatchConnectivityRPCRepository` to `WatchConnection`
- Request/response uses associated types instead of separate protocols
- All APIs are async/await instead of completion handlers
- Requires iOS 17.0+ / watchOS 10.0+ / Swift 6.0+

## API Overview

```swift
// Define requests
struct FetchRecipeRequest: WatchRequest {
    typealias Response = Recipe
    let id: String
}

// Register handlers
connection.register(FetchRecipeRequest.self) { request in
    return try await fetchRecipe(id: request.id)
}

// Send requests
let recipe = try await connection.send(FetchRecipeRequest(id: "123"))

// Shared state
let settings = SharedState(initialValue: Settings(), connection: connection)
try settings.update(newSettings)
```
