Apex Notes 0.1.6

Fixes

• Rebuilt the macOS DMG from a verified signed app bundle so the website install command can pass strict codesign verification again.
• Added a release packaging script that signs the app, regenerates the DMG, mounts it, and verifies the app inside the DMG before upload.

Verification

• npm test
• cargo check --manifest-path src-tauri/Cargo.toml
• APEX_NOTES_ALLOW_ADHOC=1 npm run package:mac
