Build the app and notification extension for Mac Catalyst with the Mac
idiom, so Macs get a 1:1 native window instead of the scaled iPad app.
The Mac build keeps the run.hapi.app bundle ID and adds Mac entitlements
(sandbox, network, microphone, user-selected files, Mac APNs).
- Always use the split on Mac with a sidebar list style, denser rows,
14pt reading text, a hidden duplicate titlebar title, a minimum window
size and page-sized sheets; open web links in the default browser and
hide the unavailable live QR scanner.
- Add menu bar / hardware-keyboard commands: New Session, Settings,
Toggle Sidebar, a Session menu (settings, files, rename, export, stop,
previous/next session) and a guide link.
- Composer: Return sends on Mac (Shift/Option-Return for a newline, IME
untouched, first suggestion picked); dropped files and pasted images or
copied files become attachments on all platforms.
- CI builds Mac Catalyst and runs the navigation, split and transcript
geometry tests there; README documents the Mac build.
