Advertise only the capability this server actually has

Browse source 
The gem's default_capabilities advertises tools, prompts, resources and
logging. This server has only tools; logging is additionally deprecated as of
2026-07-28 (SEP-2577).

Passing capabilities: { tools: {} } makes server/discover honest. No
listChanged flag, because change notifications at this revision are delivered
over subscriptions/listen and this server does not serve it.
