Fix parallel tool calls in multiple parsers
MiniMax M2, Seed OSS:
- Default allow_additional to true per JSON Schema spec
- Add trailing p.space() after tool_close to consume whitespace between calls
Functionary V3.1:
- Remove overly strict python tool validation that rejected multi-arg tools
- Add needle_tool_name config to avoid triggering special python handling in tests
Qwen3 Coder (partial):
- Default allow_additional to true
- Add <tool_call>/</ tool_call> wrapper matching
- Use p.space() instead of literal spaces for flexibility
Note: Tool call scenarios still failing - needs deeper investigation
