Without this: --tool-call-parser qwen3_coder causes api_server.py to crash
with KeyError at line 537: 'invalid tool call parser: qwen3_coder'
This is AFTER the --reasoning-parser crash (fixed in b446763) - even if
argparse passes, this KeyError kills the server.
Qwen3 models use Hermes-compatible tool calling format:
<tool_call>{"name": "func", "arguments": {...}}</tool_call>
So registering qwen3_coder -> Hermes2ProToolParser is semantically correct.
This was the SECOND startup blocker preventing the benchmark task from
completing. The first was --reasoning-parser (fixed). Together these
explain why task_id=3905102 has been stuck at status=running for 84+ minutes.
Startup sequence that was failing:
1. argparse --reasoning-parser qwen3 -> CRASH (fixed b446763)
2. ToolParserManager.get_tool_parser('qwen3_coder') -> KeyError (fixed NOW)
3. Qwen3_5MoeForCausalLM not in registry -> crash (fixed 08dc010)
All three must be fixed for the server to start.
