Starling: The first real desktop written by AI

Nicely done! This is an example of how engineering discipline mixed with good agent guidance can avoid the slop.

A couple of things:

- The test pyramid (static -> unit -> functional -> VM release gate) works but is dependent on someone remembering to run it locally. Some kind of CI would help here.

- The C++ Swift interop layer has some huge files. Understandable given that you're porting the framework rather than reimplementing it, but right now it's the least documented, most god-object part of the codebase.

So this is yet another Linux desktop environment (DE) But with “AI”.
