Subject: [PATCH] feat(lang/omnisharp): switch neotest adapter to vstest
 (#6540)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Description
Replace `neotest-dotnet` with `neotest-vstest` in the Omnisharp extras.

The maintainer of `neotest-dotnet` has announced possible archiving and
recommended moving toward a vstest-based approach
(see Issafalcon/neotest-dotnet#142).

In addition, `neotest-dotnet` often fails to reliably discover tests
(currently reproducible), while `neotest-vstest` works consistently in
those same scenarios.

`neotest-vstest` delegates to Microsoft’s VSTest engine, which provides:

- Framework-agnostic discovery and execution (xUnit, NUnit, MSTest,
etc.)
- Support for both C# and F#
- Parameterized test support
- Compatibility with Microsoft.Testing.Platform going forward

According to the `neotest-dotnet` maintainer, this vstest-based approach
is more reliable and maintainable than parser-based discovery and is the
recommended path going forward.
