Implements the async message handler proposal from #2215 and exposes additional MQTTnet features as PowerShell cmdlets.

Core Implementation

RegisterMqttMessageHandler - Async handler with proper runspace management:

Executes ScriptBlock in captured runspace via Task.Run
Passes ($topic, $payload, $message) to handler
Error output to host stream without blocking event thread

Register-MqttMessageHandler -Session $session -Action { param($topic, $payload, $message) Write-Host "Received on $topic: $payload (QoS: $($message.QoS))" }

Connection Enhancements

Connect-MqttSession - Added transport and protocol options:

WebSocket: -WebSocketUri "ws://broker:8000/mqtt"
TLS: -UseTls -AllowUntrustedCertificates
LWT: -WillTopic, -WillPayload, -WillQoS, -WillRetain
Tuning: -KeepAlivePeriod, -Timeout

Publishing Enhancements

Publish-MqttMessage - MQTT 5 user properties:

$props = @{ "source" = "PowerShell"; "version" = "1.0" } Publish-MqttMessage -Session $session -Topic "data" -Payload "test" -UserProperties $props

New Cmdlets

Get-MqttSessionStatus - Connection state
Test-MqttConnection - Broker ping with timeout
Unregister-MqttMessageHandler - Clear all handlers
Show-MqttExamples - Quick reference

Documentation

README.md with examples and parameter documentation
Test.ps1 with comprehensive usage scenarios
SmokeTest.ps1 for validation

Total: 13 cmdlets (7 new, 2 enhanced, 4 existing)
