fix: emergency memory optimization to prevent Stack-Heap Collision

CRITICAL FIX: Main Controller experiencing Stack-Heap Collision from verbose logging

- Added emergency memory monitoring to auto-disable verbose logging when memory low
- Replaced heavy string concatenation debug calls with lightweight versions
- Added memory checks before debug output to prevent crashes
- Simplified verbose logging toggle messages to reduce memory usage
- Emergency threshold: auto-disable at <1000 bytes free memory
- Safety checks: only output debug if >500 bytes available

This should immediately resolve the Stack-Heap Collision error.
