Implement 3 new MCP tools that query live application state via Inspector API:
- inspect_config: view app params, DI config groups, event listeners
- inspect_routes: list routes with filtering, check route matching
- inspect_database_schema: table list with sizes, column/index details

Add InspectorClient HTTP client (file_get_contents, no ext deps).
Wire into all adapters (Yii3, Symfony, Laravel, Yii2), CLI, and standalone.
29 new tests (148 total McpServer tests passing).
