Fabien F. a625b065cf feat: start the game client under umu-launcher / Wine on Linux
client::launch started Ascension.exe directly, which cannot work on Linux, and
client::is_running found nothing (it reads the Windows process list). wine.rs is
the Linux counterpart, and both hand over to it on a Linux host.

It runs the command of the project's own launcher script: umu-run with a Proton
build (GAMEID=0, PROTONPATH, WINEPREFIX, started from the client folder), else
plain Wine, with WINEDLLOVERRIDES=divxtac=d (DivxTac.dll deadlocks the world
loading screen under wine-mono). The newest GE-Proton found for Steam is used, or
umu's own choice; COA_PROTONPATH, COA_WINEPREFIX and client-launch.json override
the detection; the prefix defaults to ~/Games/umu/coa-client. The game runs in its
own process group, so closing the Manager does not close it, and prints to
client.log. Whether it runs is read from /proc, where the command line holds the
Windows form of the client path. A clear message says what to install when neither
umu nor Wine is found.

Tests: detection (newest build, no build, Wine only, nothing, overrides), the
command, the /proc match, and a real spawn with a stand-in umu-run that records its
environment. Not run: the real client.
