macOS: ship solidcraft-cli inside SolidCraft.app (#1456)

Every other package (AppImage, deb, rpm, tar, Flatpak, Snap, MSI, portable zip, FreeBSD) already
puts solidcraft-cli next to the app; the macOS bundle only had it in a separate zip. The agent
chat starts it as its agent's MCP server and looks for it beside the running program.
