Fix CI builds for Windows and macOS

- Drop Windows appx target: requires MS Store signing creds CI lacks,
  causing the release workflow to fail.
- Clean up macOS DMG signing: set identity:null, hardenedRuntime:false,
  gatekeeperAssess:false, dmg.sign:false. Prevents the quarantine
  "AutoNote.app is damaged and can't be opened" error on install.
- Fix mac.target to use array form (was a bare object).
- Bump version 0.11.0 → 0.12.0 to match release tag.
