Add Nebula.Windows with Sway IPC backend

Introduces a new `core/windows` module (`Nebula.Windows`) with `WindowService`, window/workspace models, and a Sway IPC backend for live window tracking and control (focus, close, move/resize, snap, maximize/restore, minimize, workspace switch). The desktop shell now links this module, uses compositor focus for top-bar active app text, and adds an Open Windows section in the launcher with focus/close actions.

Also updates application metadata handling to parse `StartupWMClass` and map window `app_id`/class to friendly names and icons, and revises Sway config/docs for the new floating-first Desktop 0.2 behavior with temporary compositor-provided decorations.

# Sway is invisible infrastructure. Nebula Desktop is the visible shell.
# Do NOT add a bar block; Nebula provides its own top bar.
#
# Nebula Desktop 0.2 is floating-first: ordinary application windows open
# as independently movable/resizable floating windows, not tiled to fill
# the workspace. Sway remains the temporary compositor/window manager.
# Custom Nebula window decoration is later work.
