v0.2.0 test build 4: the app updates itself

Test build 4 of the no-Terminal app. Please report what happens.

Download bo2-mac.zip, double-click it to unzip (the unzip command breaks the signature: use Finder or ditto -x -k), then open Black Ops II.app.

On test build 1, 2 or 3: download this one by hand, once. From this build on, the app tells you when a new one is out.

New since test build 3:

• The app looks for a new release once a day at launch, shows what is new and offers to install it. It installs only a build signed and notarized by the same developer. "Install, keep this version" keeps the current app beside it, renamed with its version: opening that one goes back.
• A change to the patches of the translation tools now reaches existing installs: the modes they affect are converted again.

Unchanged:

• Requires macOS 26 or later on Apple silicon. On macOS 14 or 15, keep the Terminal install from the README.
• Signed and notarized (Developer ID, Adrien Robino). No Homebrew, no Terminal: the app carries its own translation tools. macOS may ask you to install Apple's Command Line Tools.
• Contains no game file and no translated game code. You still need your own Steam copy and the three decrypted executables described in the README.
• Updates redo only what changed: a fix to the runtime relinks the three modes in about 3 minutes.

Checked on an M1 (16 GB, macOS 27.0.1): the update check against the published releases (install, keep the old version, later, already up to date, a tampered download refused), with test build 3's notarized download installed over an older app. The conversion and Play path are those of test build 3. A match from this app has not been played yet: please tell us if it works for you.
