RegisteredToolAdapter previously defined renderCall/renderResult as
prototype methods that unconditionally delegated to the underlying
definition. When the definition had no renderers, these methods still
existed on the instance, causing ToolExecutionComponent to enter the
custom-renderer path, receive undefined, and silently discard tool
result text — extensions without renderers showed blank output.
Move render methods to instance properties assigned only when the
definition actually provides them, so the absence check in
ToolExecutionComponent works correctly.
