Unfocus v0.6.0-beta.2

These prerelease builds are not notarized. macOS app bundles are ad-hoc signed rather than Developer ID-signed, and Windows installers are not code-signed. Verify downloads with SHA256SUMS and the GitHub build-provenance attestations.
The release also includes a CycloneDX SBOM and the bundled third-party notices.

• Linux: X11 is qualified. APT archive metadata is signed; application binaries are unsigned. Wayland is unsupported.
• macOS 11+: Preview, ad-hoc signed, and not notarized. Uses the system-provided AppKit and WebKit frameworks; multi-monitor behavior is not yet qualified.
• Windows: Idle and fullscreen probes are implemented, but interactive multi-monitor qualification is pending.

Changes

Changed

• macOS release notes, install guidance, and repository release policy now say
  exactly what ships: the app bundle is ad-hoc signed so its package signature
  can be verified locally, but it is still not Developer ID-signed or
  notarized, and first-launch Gatekeeper warnings still apply.

Fixed

• Tauri macOS packaging now requests an explicit ad-hoc app-bundle signature
  instead of leaving the bundle in the linker-signed state. The packaged
  .app now binds Info.plist, seals resources, and passes strict deep
  codesign verification on Apple silicon.
• Release automation now verifies the real Tauri-reported macOS .app bundle
  before artifacts are uploaded, so a linker-only macOS package cannot ship
  unnoticed again.
