Fix: Synthesize handlers for empty tool/prompt/resource collections ( #865 )
...
* Initial plan
* Allow handlers for empty tool/prompt/resource collections
Changed condition from `IsEmpty: false` to `not null` check in McpServerImpl.cs for resources (line 298), prompts (line 459), and tools (line 547). This allows handlers to be synthesized even when collections are empty, enabling dynamic addition of items after initialization.

Decouple Handlers and Collections from protocol types ( #765 )

Also, Fix ListResourceTemplatesHandler issue.
