v0.12.0 — Concierge is the app; agent CLI is concierge-cli

One app, Vortex-style

concierge (concierge.exe) is now the whole app: launching it opens the window, starts the download service in the same process, and puts a Concierge icon in the tray. Quitting stops everything; hiding to the tray (click the icon) keeps downloads running. Launching it again while it's open just raises the existing window — no second windows, ever.

• One-click downloads now register the app itself as the nxm:// handler (Settings → Enable 1-click downloads to re-register).
• The command-line tool is concierge-cli — used by the AI assistant inside the sandboxed shell. Typing concierge <command> still works and forwards to it, so existing packs and habits keep working.
• Updating from an older version is seamless: the updater understands both layouts, your Start-menu/desktop shortcuts keep launching the current build, and old nxm:// registrations keep working until you re-register.

Under the hood: the standalone daemon is no longer spawned (it ships only for backward compatibility), the updater handles the rename transition with tests covering every install layout, and the sandbox keeps concierge … meaning the CLI for provisioned packs.
