Code Review

This pull request transitions the MCP server and tool definitions from V1 to V2, standardizing on snake_case for property names and updating tool identifiers like create_analysis_session and session_id. The changes span schemas, handler logic, and service types to ensure consistency with the new Spotter 3 agent workflow. Review feedback highlights an opportunity to improve maintainability by renaming internal handler methods to match the new tool names and identifies invisible characters in schema descriptions that require removal.
