refactor(mcp): Remove unused executeMCPToolAction utility

The  function aimed to abstract the common flow within MCP tool  methods (logging, calling direct function, handling result).

However, the established pattern (e.g., in ) involves the  method directly calling the  function (which handles its own caching via ) and then passing the result to . This pattern is clear, functional, and leverages the core utilities effectively.

Removing the unused  simplifies , eliminates a redundant abstraction layer, and clarifies the standard implementation pattern for MCP tools.
