server/session_manager.py
Manages the Session 1 → Session 2 transition.
Key responsibilities:
1. Wipe the filesystem: code written in Session 1 does NOT persist.
2. Preserve the task description and test suite (Session 2 must implement).
3. Randomize function/class names again so Session 2 cannot reconstruct
from Session 1 code memory (they share the handoff note only).

Handles the controlled transition between sessions.
After transition:
- task.files reset to starter_code (blank implementations)
- task description preserved (Session 2 sees the original task)
- test suites preserved (same tests run at submit)
