Inconsistent hook system - Mix of Node.js and Python scripts

[AmbushData]

Problem

The hooks system has both Node.js (.js) and Python (.py) implementations, causing confusion and potential execution issues.

Current State

• Python scripts: scripts/hooks/session_end.py, scripts/hooks/suggest_compact.py
• JavaScript scripts: scripts/hooks/session-end.js, scripts/hooks/suggest-compact.js, scripts/hooks/evaluate-session.js
• Shell scripts: hooks/memory-persistence/session-end.sh
• hooks.json: References Python scripts in some places, Node.js in others
• hooks.json.backup: Contains old Node.js references

Expected State

• Consistent language choice (Python preferred based on conversion)
• Remove duplicate implementations
• Update all hook references in hooks.json
• Clear documentation on which scripts are active

Impact

• Runtime Issues: Users may not have both Node.js and Python available
• Maintenance: Duplicate code in two languages
• Confusion: Unclear which scripts are actually being used

Files Affected

• scripts/hooks/*.js (7 JavaScript files)
• scripts/hooks/*.py (2 Python files)
• hooks/hooks.json
• hooks/hooks.json.backup
• hooks/memory-persistence/*.sh

Suggested Approach

1. Complete Python conversion of all hooks
2. Remove JavaScript hook implementations
3. Update hooks.json to use Python exclusively
4. Remove hooks.json.backup
5. Document hook dependencies in README
