fix: improve stuck detection to track failed tool calls

Browse Source 
- Track failed tool calls in call history (parse errors, execution errors)
- Increment turns counter for failed tool calls too
- Stuck detection now works even when tools fail repeatedly
- Inspired by Ruflo and Hermes Agent best practices

Fixes the bug where zCode would get stuck in infinite loops when tool calls fail.

Test results: ✅ All stuck detection tests passing
