SIGSWON 5.0.0.35 - development release

- Game owners now hear the three-note game alert when a new join request needs
  approval. Enable sound effects in Preferences > General. Existing saved sound
  and mute settings apply, and sounds remain off by default for new settings.
- A pending host-approval request flashes the lobby taskbar button while the
  application is in the background or minimized. The visual alert works even
  with sounds off. It does not force window activation or restoration.
- Flashing stops when you return to the application, answer/cancel the request,
  the request expires or disappears, the connection is lost, or the client closes.
- Duplicate, wrong-game, self, nonhost, policy-filtered and Autojoin requests
  do not create host approval alerts.
- The host sound takes priority over chat/presence events. One host alert can
  wait behind a playing cue so opening the approval dialog does not lose it.
- Retains the four original custom sounds, clear News & Info checkbox, updater
  progress, Join Game selection correction and prior improvements.

VALIDATION
46 focused regressions and 9 first-install checks pass, along with native menu,
signing and scanner regressions. XP production-TLS builds, DLL load/unload,
export and import gates pass. The final updater is verified with the pinned
RSA public key, and its DLLs match the manual archive. Final public artifacts
are scanned with Microsoft Defender before publication.

Actual audible output and visible taskbar flashing on the XP VM remain pending
acceptance. Automated sound/taskbar lifecycle checks use simulated Windows API
calls; they do not certify an audio device or shell animation. The existing join
approval countdown, accept/decline, disconnect and expiry flows are exercised.

Close the game and launcher before installing. Replace both DLLs in the BASE
game folder only. Leave OPU unchanged and keep .sigswon-update-* backups until
you have tested the game. Use SIGSWON-5.0.0.35-Setup.exe for first installation,
or the manual DLL ZIP. The SIGSWON-client-update-5.0.0.35.exe payload is for the
existing in-client update flow, not standalone setup.

The setup and DLLs are not Windows Authenticode-signed. The update package uses
the existing SIGSWON RSA/SHA-256 signature; these are separate mechanisms.
