refactor(toolcall): enhance tool call extraction with multiple keywords and safety limits

Browse Source 
- Add support for multiple keywords: tool_calls, function.name:, [tool_call_history]
- Add OOM protection with search limits in extractToolCallObjects
- Add max scan length limit in extractJSONObject to prevent OOM on unclosed objects
- Update tool_sieve to handle more tool call patterns
- Add loose JSON repair in parseToolCallPayload for better error recovery

This improves DeepSeek tool call parsing robustness.
