Add ToolInjectionMiddleware + Tools for Read/List Resource/Prompt for Client Compat (#2142)
* Add compatibility tools contrib module

Implements four standalone tools that expose resources and prompts
as callable tools for clients that only support the tools capability.

Features:
- list_resources: List all available resources
- get_resource: Read a resource by URI
- list_prompts: List all available prompts
- get_prompt: Get a prompt with optional arguments

The tools use Context to access the server instance and can be easily
added to any FastMCP server using the add_compatibility_tools helper
or by adding individual tool instances directly.

* Simplify compatibility tools to return raw MCP protocol objects

Return raw MCP protocol objects (ListResourcesResult, ReadResourceResult,
ListPromptsResult, GetPromptResult) instead of custom dictionaries. This
makes the tools simpler and more predictable by directly exposing what
the client methods return.
