GENERATE_INFOPLIST_FILE = YES with no INFOPLIST_FILE meant Xcode
synthesized Info.plist purely from INFOPLIST_KEY_* build settings and
silently ignored oAI/Info.plist on disk — so CFBundleHelpBookName/
CFBundleHelpBookFolder never made it into the built app. NSHelpManager
therefore couldn't resolve the book and macOS showed the generic Help
Center instead of oAI's help content (previous commit 74c8be8 fixed
openHelp() to call NSHelpManager, but that call had nothing to find).
Fix: point INFOPLIST_FILE at oAI/Info.plist so Xcode merges its extra
keys into the generated Info.plist, and add a synchronized-group
membership exception so Info.plist isn't also copied into Resources
(would otherwise produce a duplicate-file build warning).
