Expose internal stack introspection APIs as a statistical runtime analysis tool

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.

Inizia leggendo il modulo _remote_debugging esistente e le PRs collegate elencate nell’issue, poiché sembrano contenere il lavoro di implementazione in corso. Determina quali API di introspezione dello stack e quale comportamento dell’observer sono previsti prima di stimare l’ambito; l’issue sarà completa solo quando lo strumento di analisi a runtime concordato potrà collegarsi a processi Python in esecuzione e raccogliere le statistiche specificate senza modifiche al codice o riavvii.
