pj 92b446973f feat(appstore): add a Mac App Store build track
Tauri has no App Store target, so mas-package.sh covers the distance between the .app and something
App Store Connect will take. The order is load-bearing: the provisioning profile goes in before
codesign runs because the signature covers it, which is also why Tauri's own signing is switched
off for this build.

The sandbox costs three things, all Apple's rules rather than choices. The updater is gone, and
falls out for free because the plugin was already conditional on the config declaring it; only the
release overlay does. The Check for Updates menu item is gated on the same condition, since a menu
item that errors when clicked is its own rejection risk. The library moves into the container, and
the system spelling dictionary becomes unreadable.

Two things the first upload taught us. The profile is kept owner-only where it lives next to the
signing keys, and cp carried that mode into the bundle; Apple rejects a package containing anything
a non-root user cannot read. And altool exits 0 after printing UPLOAD FAILED, so its exit status
cannot be trusted and the transcript is the only reliable signal.

# The certificates go into a keychain that exists only for the length of this run, and the login
# keychain is never written to. That keeps a machine that has signed once from quietly being able
