fix(launcher): handle Game-z.exe builds and ignore extendtext.exe

Soulstones 1 ships `Game-z.exe` rather than `Game.exe`. Find-GameExe preferred
`Game.exe` and otherwise fell back to the shallowest non-ignored .exe, which for
that build resolved to `extendtext.exe` — a dev tool that was missing from the
ignore list — instead of the real launcher.

Add extendtext.exe to $ignore and replace the single-name preference with a
$launcherNames list (Game.exe, then Game-z.exe) before the shallowest-exe
fallback.
