Add memory monitoring system to prevent heap out of memory errors: - Real-time heap usage tracking with configurable thresholds - Three alert levels: warning (60%), compact (70%), critical (85%) - 30-second minimum interval between automatic compactions - Proactive compaction triggered when memory usage exceeds 70% - New '/compact memory' command to check heap usage This addresses the V8 heap out of memory crash that occurs during long-running sessions with large conversation histories. Files: - src/memory-monitor.ts: New memory monitoring system - src/agent.ts: Integrate memory monitor and add proactive compaction - src/commands/compact-commands.ts: Add memory subcommand - src/index.ts: Add memory status display handler Wingman: Codi <codi@layne.pro>
Fix E16 error by using correct snake_case property names from Node.js v8 API: - Fix property names: used_heap_size, heap_size_limit, etc. - Use proper ES module import for v8 - Add additional utility methods: isCritical(), getDetailedSnapshot() - Test confirms memory monitor works correctly Build and all 324 tests pass successfully. Wingman: Codi <codi@layne.pro>

Summary
Add memory monitoring system to prevent heap out of memory errors during long-running Codi sessions.
Problem
V8 heap OOM crashes occur when long-running sessions accumulate large conversation histories (~4GB heap limit).
Solution
Added memory monitoring with:
Files
Testing
Usage
/compact memory shows heap usage and stats
