Walkthrough

Updates PytestFullSuiteHandler to treat missing session_id as a new command, swallowing it without mutating state. With session_id present, it uses per-session state to prevent repeating the last command. Tests added to validate behavior for missing session_id scenarios and ensure no state leakage.

Poem

In burrows of code, I twitch my nose,
Guarding sessions where the logic flows.
No ID? I nibble, then let it pass—
No crumbs of state on meadow grass.
With keys in paw, I track the run,
One hop per command—no double sun. 🌕🐇

Pre-merge checks and finishing touches

After reviewing this pull request, I've decided to reject it due to significant functionality loss. While the PR addresses the issue of handling missing session IDs to prevent state leakage, it does so by removing important functionality including:

1. Time-based session state management (TTL)
2. Memory usage limiting (max sessions)
3. Advanced command extraction logic
4. Several important test cases

The original implementation provided important memory management features that prevent potential memory leaks in long-running applications. A better approach would be to add the missing session ID handling to the existing, more robust implementation rather than replacing it with a simplified version.

The changes go from 604 lines to 298 lines, removing critical features for memory management and session handling. This represents a regression in terms of system stability and performance.

Please consider implementing the missing session ID fix in the context of the full, more robust implementation to maintain all existing functionality while addressing the specific issue identified.
