ci(desktop): discover main-process tests instead of listing them (#576)

test:desktop listed 40 of the 49 Electron main-process test files by hand,
and the five ACP tests that need the desktop working directory ran in a
second command. Four files were missing from both lists
(desktop-device-model, edit-context-menu, rpc, window-lifecycle), so the
desktop build never ran them.

The first command now runs everything under apps/desktop/src/main and
ignores only the five tests the second command runs with --cwd
apps/desktop. The renderer tests and the sidecar step are unchanged, and a
new main-process test is picked up without editing the script.
