fix: build palette launch items for the focused Canvas card master

Fourth review round: the Launch Agent item factory only looked at selectedTerminalWorktree, which is nil in Canvas, so the palette showed no launch rows there even though the launch action itself already resolves to the focused card. The factory now mirrors the action's target resolution (selected terminal worktree, else the action-target worktree the palette already threads through). Canvas regression test included.
