initial commit: reforgermods.net launcher 0.1.0

A desktop server browser for Arma Reforger, built on the reforgermods.net v2
API. Live server list with search, sort and filters; a detail inspector with
population history and mod readiness; measured ICMP latency; favorites, recents
and settings; and direct joining through Steam.

Tauri 2 and Rust, with a Preact frontend that builds to 80 KB of JavaScript in
one chunk. Logic lives in rfm-core, which has no Tauri dependency and is tested
directly; src-tauri is the window, the command surface and the wiring.

Packaged for the public beta: a per-user NSIS installer, a portable .exe and an
Arch package, with signature-verified background updates on Windows and a
release pipeline that builds from a tag. The artifacts are not yet
Authenticode-signed — that is wired and waiting on an Azure Trusted Signing
identity, and docs/distribution.md says so plainly rather than letting anyone
discover it at the SmartScreen dialog.
