Fixes window layouts that moved windows without reliably resizing them: Left Half and Right Half now apply and verify the complete frame, and Center now produces a centered two-thirds layout.
Also fixes radix parsing, case-insensitive plugin keywords, duplicate plugin-name collisions, and deep menu walking. Hardware coverage now exercises app launch, file and Spotlight search, menu actions, clipboard, plugins, window switching, volume restoration, and exact left/right/center frame round trips.
The release script now emits both a versioned archive and a stable Beckon.zip asset.
