Agent tools can now find Raster's sign-in by themselves

Point a client at Raster and it can work out how to connect on its own — where to register, how to sign in, and how to disconnect — without anyone pasting endpoints into a config file.

What's new:

• A published connection guide agents can read. raster.app/auth.md describes Raster's sign-in flow in plain markdown, so tools that look for it can set themselves up unattended.
• Fewer setup steps. Connection metadata now points clients straight at Raster's sign-in server, so most clients need nothing but the server URL to get going.
• Desktop and native clients. Apps that hand sign-in off to a native window complete the round trip and land back where you started.
