Pull request overview

This PR extends the language-server service model generator’s Listener model to carry the concrete listener type name (e.g., Listener, WebSocketListener) as an explicit property, and uses that value when rendering listener declarations/expressions and when building listener models from source.

Changes:

• Add a new listenerType property to the Listener model and populate it across listener-model creation paths.
• Update listener declaration/expression rendering to use protocol:<listenerType> instead of hard-coding protocol:Listener.
• Update JSON test fixtures for get/update/listener-from-source scenarios to include the new property and request type.
