mcp: new API for features (#88)

Browse source 
BREAKING CHANGE

Change the API for adding tools, prompts, resources and resource
templates to a server.

The ServerXXX types are gone along with the plural Add methods
(AddTools, AddPrompts etc.)
Instead there are single Add methods (AddTool, AddPrompt).
In addition, instead of NewServerTool, there is AddTool[In, Out].

Fixes #73.
