Bookworm's plasma-workspace ships only the X11 session; the Wayland session (plasmawayland.desktop) lives in the separate plasma-workspace-wayland package (a Recommends of plasma-desktop, now listed explicitly for the same determinism as the explicit sddm). The package does not exist on trixie, where plasma-workspace integrates Wayland natively, so naming it off-bookworm would fail the apt transaction: resolve it once per installer with _kde_wayland_pkg() and build the package list in a conditional array so neither the pre-apply summary nor the apt command ever shows an empty argument. Also correct the header comment: bookworm still defaults SDDM to the X11 session, while trixie makes Wayland primary (plasma.desktop in wayland-sessions) with plasmax11.desktop as the X11 fallback. Replace the hard-coded SDDM autologin session cascade with an existence-based ordered probe (_sddm_session_candidates) that prefers Wayland across releases, keeps the LXQt sessions last for when the module starts offering LXQt, and reads its session roots from SESSION_DIR_WAYLAND / SESSION_DIR_X11 for hermetic testing. Extend tests/desktops.bats with 13 offline tests: gate helper output on bookworm/trixie, captured apt commands for both installers, summary content (no empty package line), and the ordered session probe against fixture trees.
