Remove Inspiration Library

Disconnect an external inspiration library so Lazyweb design skills no longer search it.

Workflow

1. List Connected Libraries

cat ~/.lazyweb/libraries.json 2>/dev/null || echo '{"libraries":[]}'

If no libraries are connected, tell the user: "No inspiration libraries are connected. Use /lazyweb-add-inspo-source to connect one."

2. Ask Which to Remove

If the user didn't specify, show the list and ask which library to disconnect. If only one library is connected, confirm they want to remove it.
