feat!: improve schema_utils, generqted new schema sets

[hashemix]

📌 Summary

This PR introduces significant improvements to the generated schema, with a particular focus on schema_utils.
The key changes in schema_utils include refactoring structs and enums to better support the new MCP 2025-11-25 version, as well as removing many trait implementations that are no longer necessary under the new architecture. As a result, the new version is more lightweight and maintainable.

✨ Changes Made

• Refreshed the generated schema to align with the latest updates to the official specifications.
• Updated method constants to return &'static str instead of String.
• Refactored FromMessage and ToMessage implementations for requests and notifications.
• Simplified message handling in the examples.
• Simplified TryFrom implementations by matching directly on variants instead of using intermediate enums.
• Added request_id() methods to ServerRequest and ClientRequest.
• Enhanced RpcError with builder methods and improved error handling.
• Removed redundant nested matches in TryFrom implementations for results and notifications.
• Refactored code snippets for message handling, initialization, and response detection to use direct enum matching and new structs (for example, ServerJsonrpcResponse and ClientRequest::InitializeRequest).
• Improved clarity and readability in client-side message handling examples.
• Refined build scripts to improve feature-specific testing and linting.
