fix(release): publish versioned installers and refine desktop updates

[kev1n77]

Summary

• Publish the standalone Windows installer with a versioned filename:
  BitFun_<version>_windows-x86_64-installer.exe.
• Add manual_installers.windows-x86_64 to latest.json while keeping the
  automatic updater package under platforms.windows-x86_64.
• Update the openbitfun.com mirror flow to synchronize the versioned installer,
  rewrite its URLs, generate website download metadata, and retain the legacy
  fixed-name fallback.
• Explicitly generate production or development version metadata and make
  generation failures stop the build.
• Make the desktop About dialog use the native application version and append
  -dev only in development builds.
• Change the Windows updater NSIS install mode from passive to quiet.

Fixes: N/A

Type and Areas

Type:

Bug fix / CI

Areas:

Desktop/Tauri, web UI, installer, release workflows, update metadata, and
openbitfun.com mirror synchronization.

Motivation / Impact

The standalone Windows installer previously used a fixed filename and was not
represented separately in latest.json, making version-specific domestic
mirror synchronization unreliable.

Production builds could also reuse development version metadata, causing the
About dialog to display a -dev suffix. In addition, automatic updates launched
NSIS in passive mode, which displayed a second installation progress window
after BitFun's own download progress UI.

After this change:

• Each release publishes a versioned standalone installer and signature.
• Manual installer consumers and mirrors can use
  manual_installers.windows-x86_64 without changing the Tauri updater URL.
• Release version metadata is checked for consistency before publication.
• Production builds display the native packaged version without -dev.
• Newly built clients install future Windows updates silently after download.

Reviewer Notes

manual_installers is an additional manifest field intended for website and
mirror consumers. Tauri automatic updates continue using
platforms.windows-x86_64.url.

An existing installation may still show the NSIS progress window when upgrading
to the first release containing this change, because that update is launched by
the older client using its embedded passive configuration. Updates launched
by the newly installed version will use quiet mode.

The updated scripts/openbitfun-release-sync.sh must be deployed to the domestic
mirror server before the new manual installer metadata is used there. The script
retains compatibility with releases that only contain the legacy
bitfun-installer.exe asset.

Rollback can be performed independently through the three commits covering
release metadata, About dialog version handling, and updater install mode.
