SoulPlay experimental XP / Windows 7 launcher - test 1

This ONE EXE selects Java for XP, Windows 7, or newer Windows automatically.
XP SP3: install Microsoft .NET Framework 4.0 FULL (not Client Profile) first.
Windows 7 SP1: .NET Framework 4.8 is recommended; .NET 4.0 Full is the minimum.
Modern Windows: use the normal launcher for everyday play.

1. Download SoulPlayLauncher-XP-Test.exe from the SoulPlay download page.
2. Open it normally. It does not require an administrator account.
3. It checks a signed release, downloads the client and appropriate Java, verifies
   the cache and opens the game. Keep application/cache folders between attempts.
4. Interrupted downloads retain verified 1 MiB blocks. Reopen to continue.
5. If it fails, send the Windows version/service pack, 32/64-bit, and these logs:
   %LOCALAPPDATA%\SoulPlay\xp-test-updater\launcher-error.txt
   %LOCALAPPDATA%\SoulPlay\xp-test-updater\client-*.log
   On XP this is normally under Documents and Settings\<user>\Local Settings\Application Data.
   Cache log: <user-home>\SoulPlay-live-v35\soulplaycache\cache-update.log
   Do not send account passwords or private files.

Diagnostics: SoulPlayLauncher-XP-Test.exe --verify-only checks launcher downloads.
SoulPlayLauncher-XP-Test.exe --repair verifies/repairs cache without entering gameplay.

This build targets .NET 4.0 and includes managed TLS 1.2 with certificate-chain,
hostname and expiry checks. The update signing key and per-block SHA-256 checks
remain enforced. XP uses archived Azul Zulu Java 8u202 x86, with a refreshed CA
trust store. Windows 7/newer use the current x86/x64 runtime packages.
XP disables optional Discord Rich Presence and uses the existing software renderer.

IMPORTANT: This is an experimental legacy build with an OLD Java runtime on XP.
It has NOT been validated on an actual XP or Windows 7 installation. Initial
checks were run on the developer's modern Windows host; OS compatibility testing
is the purpose of this download. The normal production launcher is unchanged.

Runtime licenses/notices and source links are included in each Java package.
