CapsuleCraft v1.12.1

CapsuleCraft v1.12.1 — Native-only releases, Integrations fixes

The headline

Releases now carry native builds only. The Tauri/web installers (MSI,
NSIS, deb, rpm, dmg) are retired — the egui shell is the app, and every
artifact on the release page is exactly that:

• Windows x64 — CapsuleCraft_native_1.12.1_x64.zip (portable, zero deps,
  no WebView2, no installer)
• Linux amd64 — CapsuleCraft_1.12.1_amd64.AppImage (zero-dependency)
• macOS — CapsuleCraft_native_1.12.1_macos_universal.app.zip — new
  universal binary: Apple Silicon and Intel in one .app

Every release also ships the mistral.rs OCR engines (mistralrs-engine-*.tar.gz,
used by the in-app Integrations catalog) and a unified SHA256SUMS.txt.

Fixed

• Integrations modal swallowed clicks. The dialog was only painted while
  a full-screen click backdrop sat underneath: poking anywhere that missed a
  button — status pills, progress bars, empty card space — closed the whole
  modal mid-interaction. The panel now claims its own click area; dismissing
  works by clicking the dimmed backdrop outside the dialog or pressing Escape.
• TTS voices could install a broken runtime. The catalog downloaded
  sherpa-onnx v2.0.1 while the FFI mirrors c-api.h at v1.12.40 (v2.0.1
  removed the data_dir phonemization argument and shifts struct layouts).
  The runtime component now downloads v1.12.40, and a regression test welds
  the URL to the FFI tag so the two cannot drift again.
• OCR engine downloads outlived releases. mistralrs-engine-*.tar.gz is
  now fetched through the releases/latest redirect instead of a hard-coded
  v1.12.0 URL.

Upgrade notes

• Web/Tauri installers are no longer produced. If you previously installed
  the web build (MSI/NSIS/deb/dmg), remove it and switch to the native
  artifacts above — the Integrations catalog and the rest of the native
  feature set live only in the egui shell.
• The macOS artifact replaces the previous arm64-only zip with a universal
  build; Intel Macs are supported again.
