Feature or enhancement

Implement a new high-frequency runtime observer that leverages the existing _remote_debugging module to collect detailed execution statistics from running Python processes. This tool enables non-intrusive observation of production applications by attaching to already-running processes without requiring any code modifications, restarts, or special startup flags. The observer can perform extremely high-frequency sampling of stack traces and interpreter state, providing detailed runtime execution analysis of live applications.
