Adds an F# MCP server project template with both local (stdio) and remote (HTTP) transport options, and updates packaging to correctly transform F# project files.
Changes:
- Introduce new F# template content for local and remote MCP servers (README, Program.fs, project files, tooling, config).
- Add MSBuild packaging support to transform
.fsproj-ininto.fsproj. - Align template grouping behavior by adding
groupIdentityto the C# template.

This pull request adds a new F# project template for creating Model Context Protocol (MCP) servers, alongside enhancements to the packaging and configuration of project templates. The new F# template supports both local (stdio) and remote (HTTP) transports, includes sample code and configuration, and aligns with the existing C# template structure. Additionally, the packaging logic in the main

The template supports both self-contained and framework-dependent builds, and provides guidance for publishing to NuGet and local development.
