Remove the .NET/WinForms project (SshHandler/, SshHandler.sln) now that
the Rust rewrite (SshHandlerRs/) covers the same behavior with a
~250KB binary and no CLR startup cost, and its Default-Apps-style
registration is confirmed working.
Rewire the release workflow to build ssh-handler.exe natively on
windows-latest with the MSVC toolchain instead of dotnet publish, and
package it alongside the .bat and .sh handlers as release assets
(ssh-handler-rs-*.exe, openssh_protocol_handler-*.bat,
ssh-handler-*.sh) when a v* tag is pushed.
