agent: Cursor Private Inference's program in a .app is named as on a Mac on any system, so TestCursorLocal passes on Linux CI — the .app fallback (no Info.plist) took product.json's applicationName as Linux names it (cursor), while a .app is a Mac's bundle and its program is Cursor. The test failed on the ubuntu CI since v0.1.877 and passes now in a linux/arm64 container (it failed there on the old code). go vet, builds (darwin, GOOS=linux nogui, GOOS=windows) and go test -tags nogui -count=1 ./... under a temp HOME pass.
