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 )
...
* Decouple Handlers and Collections (e.g. ToolsHandler and ToolsCollection) from Capabilities by promoting them to the options types.
Also, group all handlers in container classes, for server, I decided to move McpServerHandlers down to Mcp.Core and move the NotificationHandlers there too.
Also, Fix ListResourceTemplatesHandler issue.
* Add remarks for empty protocol capability types
* Keep JsonIgnore properties and mark them as Obsolete
* Continue supporting Obsolete members
* Update Obsolete messages to indicate the member will be removed
* Add EditorBrowsable Never to the remaining obsolete members
