Add compiled Windows and Linux server executables alongside the client.

Please consider adding compiled versions of the relay server with the client releases. This would make it easier to get up and running without installing Python.

Thanks for the suggestion. Today the relay ships as a small self-contained Python script (server/remsound-relay.py) with an install.sh, which covers any host that has Python 3 — Raspberry Pi OS and most server distros do out of the box.

Standalone compiled binaries — a Windows .exe and a Linux executable that need no Python installed — are a reasonable ask for running a relay on a box without Python, and I'd like to offer them. The honest catch is that it needs a real per-platform build step: the Windows .exe has to be built on Windows and the Linux binary on Linux (these can't be cross-compiled from a single machine), so the clean way to do it is a CI job that builds both on a release and attaches them as assets. It's a bit more than a quick add, so I'm leaving this open to track it rather than closing it. Genuinely appreciate the idea.
