Migrate NetDaemon to .NET 10

[Copilot]

Breaking change

None. The migration maintains full backward compatibility with existing functionality.

Proposed change

Migrates NetDaemon from .NET 9 to .NET 10 (LTS release, supported until November 2028). Updates all projects, Docker images, and CI/CD workflows to target the new framework.

Core Updates:

• SDK version 9.0.0 → 10.0.0 in global.json
• Target framework net9.0 → net10.0 across all projects
• C# language version 13.0 → 14.0

Package Cleanup:
Removed package references now included in .NET 10 framework:

• System.IO.Pipelines (4 projects)
• Microsoft.Extensions.DependencyInjection.Abstractions (1 project)
• Microsoft.Extensions.Hosting (1 project)

Docker & CI/CD:

• Updated 3 Dockerfiles to use .NET 10 SDK images
• Updated base image references from :9 to :10 (requires separate base image builds)
• Updated 3 GitHub Actions workflows to install .NET 10 SDK

Test Adjustments:
Fixed WebsocketIntegrationTests.TestWrongHostShouldThrowCorrectException() to handle .NET 10's exception behavior change where connection failures now throw TaskCanceledException instead of WebSocketException.

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
