root ee811fb308 fix: Lua adapter fixes + add ReasoningContent to CompletionResponse
- Fix syntax error: tc.function -> tc["function"] (function is Lua keyword)
- Fix empty tool_calls: Lua returns nil instead of empty table ({} vs [] in JSON)
- Fix token_usage key name in unified response (usage -> token_usage)
- Add ReasoningContent to CompletionResponse struct
- Nits: jsonTable init, import ordering
