Request: Visual Studio extension

There is currently no Prompty extension for Visual Studio. An extension would ideally be lightweight and perform the following tasks:

Essential:

• Prompty file recognition and icon for *.prompty files in Visual Studio Solution Explorer.
• Syntax highlighting equivalent to the VSCode extension.
• Published by Microsoft to satisfy compliance.

Nice-to-haves:

• Intellisense and tooltip support equivalent to the VSCode extension.
• Markdown preview support equivalent to the VSCode extension.
• File > New File template.

Less important:

• Running models or exploratory workflow features. Reasoning: VSCode is a good and widely-used platform for testing patterns and models, which is not a core competency of Visual Studio.

Didn't think I'd be using Prompty this much in the short time since its release, but I'm quite fond of it now and Visual Studio support would substantially improve the inner loop workflow. Especially since Semantic Kernel offers Prompty support.

Start by comparing the existing VSCode extension with the requested Visual Studio capabilities, especially Prompty file recognition and syntax highlighting. No files or tests are named; completion would require a Microsoft-published extension covering the essential items, with the listed nice-to-haves clarified.
