Yue-Lyu123/dsh-as-macOS

Turns the DSH Web UI into a macOS-style desktop with the chat parked behind it: Sonoma wallpaper, menu bar, magnifying Dock, F4 Launchpad, ⌘Space Spotlight, Control Centre, clock/calendar widgets, F3 Mission Control and a desktop orb that floats the native conversation back up. Finder, Terminal (a /bin/bash session) and Settings ship with the plugin; the Browser, Code, Office and Notes windows are unlocked by separate companion plugins (dsh-ego-browser, dsh-code-workbench, dsh-univer-office, dsh-obsidian-notes) and show a placeholder until installed, and the Browser window also launches a headless Chromium (found under /usr/bin, or set DSH_MACOS_CHROME). The agent can drive the desktop through /api/macos-desktop/* routes and window.__macos.
