feat(serve): serve on orcad by default on Windows too (#25162)

D7 now runs every case on Windows (orcad-serve-mode-switch-windows), including Electron
serve adopting a daemon orcad forked, so Windows no longer needs the Electron default.

+- Windows serves on orcad too. Both hosts share `<userData>\daemon`, so the daemon pipe name
+  (hashed from that path) is the same, and the relocated Electron daemon host changes only the
+  executable, not the pipe. The `orcad-serve-mode-switch-windows` e2e job gates D7 there.
 
 The slot and its pinned Node live under the desktop's `<userData>/orcad-artifacts`.

 Use only one host mode at a time. If the Orca desktop app is already sharing that computer, do not start a second `orca serve` process for the same setup.
 
-`orca serve` runs on Orca's own Node server (orcad) by default. If orcad can't serve on this computer, it uses the desktop app's server instead and prints one line saying why. On Windows it uses the desktop app's server unless you set `ORCA_SERVE_RUNTIME=orcad`, and on a packaged macOS app it currently always does, so paired clients can still update it. To always use the desktop app's server, set `ORCA_SERVE_RUNTIME=electron`.
