Pull request overview

This is a large PR that refactors the dotnet-watch Aspire integration to support macOS (and other non-Windows platforms), introduces a new three-process architecture for Aspire watch (host, server, resource), and modernizes the test infrastructure. Previously, several Aspire-related tests were restricted to Windows via PlatformSpecificFact. The PR also introduces status reporting and control command pipes for communication between the Aspire host and watch server.

Changes:

• Refactors Aspire watch into a three-process model (host, server, resource launchers) communicating via named pipes, replacing the old DotNetWatchLauncher/DotNetWatchOptions with command-based CLI (server, resource, host subcommands) and adds status/control pipe support.
• Overhauls EnvironmentOptions to derive the muxer path from SdkDirectory instead of accepting it directly, adds a configurable LogMessagePrefix, introduces notification-only MessageDescriptors (LogLevel.None), and updates ProjectRepresentation to a record struct with OS-aware path equality.
• Modernizes test infrastructure by replacing IDisposable with IAsyncDisposable, moving from BufferBlock to Channel<T> in AwaitableProcess, extracting TestEventObserver from TestReporter, splitting large test classes into focused files, and removing Windows-only test restrictions.
