v0.14.0 — rename PSLauncher.exe → PS_Launcher.exe (with backward compat)

Aligns the executable name with the repo / product naming. Backward-
compatible: existing installs that have PSLauncher.exe on disk continue
to work — the self-updater overwrites the file at the running .exe path
without renaming, so the historical filename persists on those machines.

Changes
- AssemblyName : PSLauncher → PS_Launcher (both App and Updater csproj)
- Inno Setup : MyAppExeName, MyUpdaterExeName, OutputBaseFilename all
  now use PS_Launcher prefix
- LauncherSelfUpdater : looks for PS_Launcher.Updater.exe first, falls
  back to legacy PSLauncher.Updater.exe so old installs keep updating
- Build scripts (build-launcher / build-updater / build-installer /
  build-all) : taskkill both legacy AND new names; output paths printed
  with new names
- .gitignore : added PS_Launcher.exe / PS_Launcher.Updater.exe /
  PS_Launcher-*.exe patterns alongside the legacy ones; also ignored
  the WebView2 user-data folder and Office ~$ lock files
- Server admin/launcher.php : URL pattern now generates
  PS_Launcher-{ver}.exe ; SignManifest's existing tolerant glob
  *{ver}*.exe still matches both names
- Versions bumped to 0.14.0 (App + Updater + installer .iss)

Migration story for clients
- Brand-new install via PS_Launcher-Setup-0.14.0.exe → PS_Launcher.exe
  on disk
- Existing install (PSLauncher.exe) auto-updates to v0.14 → file stays
  named PSLauncher.exe but contains v0.14 code; self-updater fallback
  ensures future updates keep working
