Reqly Desktop v0.1.0

Desktop app (Electron), arm64 only. Unsigned/unnotarized - first launch needs right-click > Open > Open anyway.

Includes T-257 (Electron runs its own server on an OS-assigned ephemeral port instead of fighting agents for 4242) and T-258 (fixes the app getting stuck on "Still trying to reach the Reqly server" when launched from Finder/Dock, caused by a PATH gap that broke the Homebrew/npm CLI spawn).
