Somnia v12.2.0-beta.10

Built from the green full-matrix CI run on 0c17a18: https://github.com/philppplik/somnia/actions/runs/39278004744 . The custom installer was built by the Windows installer workflow on the same commit: https://github.com/philppplik/somnia/actions/runs/39278009220 .

Highlights

New custom Windows setup (Somnia-Setup-preview-unsigned.exe): a branded WebView setup that hands the install over to the app. It is an unsigned Preview extra asset and has not been tested on a real Windows machine; Windows SmartScreen will warn about it. The regular x64/ARM64 setup.exe and MSI files stay the recommended install path.
The installer workflow (installer.yml) is part of the repository again, so the setup is rebuilt with every full CI run.

Tests: the update-pill end-to-end test no longer hard-codes the current beta as the "newer" release; the studio shell screenshot baselines were regenerated in CI.

Interactive Windows/macOS launch and real-device feel tests remain unverified; CI checks are not a substitute. macOS is Apple Silicon only, ad-hoc signed and not notarized: Gatekeeper may require System Settings > Privacy & Security > Open Anyway. Do not disable Gatekeeper.
Collaboration remains alpha; LAN, relay, updater installs and real provider/model quality are not certified by offline tests.
This prerelease does not replace the Microsoft Store package and ships no MSIX asset. No Store submission was made.

Windows: setup.exe/MSI (x64 and ARM64), or the unsigned Preview Somnia-Setup-preview-unsigned.exe. Linux: AppImage/DEB (amd64 and arm64). macOS: DMG (Apple Silicon), copy to Applications, follow the security exception above if offered.
