feat: MCP Tool Wrapper

[cameron-chen]

Describe the feature

Introduce a wrapper utility, similar to ToolEnvWrapper, that standardizes and unifies MCP tool execution. This wrapper should provide:

• A consistent interface for invoking MCP tools.
• Integrated access to tool-specific instructions.
• Centralized handling of tool schemas to ensure compatibility and discoverability.

Planned API:

• get_tool_instructions: return the unified tool instructions.
• get_tool_schema: Returns the tool schema in a standardized format, compatible with API-based LLM engines (e.g., OpenAI, Anthropic).

Why do you need this feature?

This feature brings follows benefits:

• Simplifies integration with different MCP tools.
• Reduces duplication by consolidating instructions and schemas in one place.
• Improves interoperability with external LLM providers.

Hey @tzyodear , good catch! I think we should remove tool response tags in the raw observation, and let the chat template adds corresponding tags. What do you think? #107
