Update test fixtures to current runtime contracts (#14259)

Recent runtime changes left the aggregate suite expecting a VS Code symlink and fixed extension version, pacman arguments without the end-of-options marker, a one-argument QML text signal, and background functions without preparation state. Align these fixtures with the current interfaces while retaining palette equality, package retry, keyboard action, and missing-background recovery assertions.
