fix: improve stuck detection to detect same tool repeated
- Previous fix required EXACT same tool call signature (including arguments) - Bot was stuck reading file in sections with different line numbers - New logic: detect stuck if SAME TOOL is called repeatedly (arguments may vary) - Extract tool name from signature and check if all recent calls use same tool - Still requires 3+ repetitions before triggering intervention This fixes the infinite loop bug when bot tries to read large files in sections. Test results: 4/4 tests passing (100%) - ✅ Same tool, different args → STUCK detected - ✅ Same tool, same args → STUCK detected - ✅ Different tools → NOT stuck - ✅ Same tool repeated at end → STUCK detected
