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.

# MCP Go SDK
***BREAKING CHANGES***
The latest version contains breaking changes:
- Server.AddTools is replaced by Server.AddTool.
- NewServerTool is replaced by AddTool. AddTool takes a Tool rather than a name and description, so you can
set any field on the Tool that you want before associating it with a handler.
- Tool options have been removed. If you don't want AddTool to infer a JSON Schema for you, you can construct one
as a struct literal, or using any other code that suits you.
- AddPrompts, AddResources and AddResourceTemplates are similarly replaced by singular methods which pair the
feature with a handler. The ServerXXX types have been removed.
