fix: remove allow_multiple_tool_calls config and simplify tool execution flow
This fixes a bug where the agent would stop responding abruptly without calling final_output. The root cause was the allow_multiple_tool_calls config option (default: false) which caused the agent to break out of the streaming loop mid-stream after executing the first tool, losing any subsequent content. Changes: - Remove allow_multiple_tool_calls config option entirely - Always process all tool calls without breaking mid-stream - Simplify system prompt generation (no longer needs boolean param) - Let the stream complete fully before continuing to next iteration - Change find_last_tool_call_start to find_first_tool_call_start - Remove parser.reset() call on duplicate detection Benefits: - Simpler logic with less conditional branching - No lost content after tool calls - Consistent behavior for all users - Reduced config complexity

When running multiple read-only commands like `ls` or `list_dir`, always run all of the commands in parallel.
