[Bug]: When user provides only part of the tool call result, ReactAgent still executes the all tools

Describe the Bug

When ReactAgent starts HITL, it returns tools pending confirmation. If the user only provides partial tool call results(e.g., the user needs to cancel part of the tool call).

ReactAgent directly enters the acting function. Within the acting function's logic, all tools from the previous round are invoked again, which may lead to unexpected calls.

agentscope-java/agentscope-core/src/main/java/io/agentscope/core/util/MessageUtils.java

Lines 47 to 64 in e68e73c

	public static List<ToolUseBlock> extractRecentToolCalls(List<Msg> messages, String agentName) {
	if (messages == null || messages.isEmpty()) {
	return List.of();
	}
	for (int i = messages.size() - 1; i >= 0; i--) {
	Msg msg = messages.get(i);
	if (msg.getRole() == MsgRole.ASSISTANT && msg.getName().equals(agentName)) {
	List<ToolUseBlock> toolCalls = msg.getContentBlocks(ToolUseBlock.class);
	if (!toolCalls.isEmpty()) {
	return toolCalls;
	}
	break;
	}
	}
	return List.of();
	}

Potentially problematic scenarios:

1. The user only wants to cancel the invocation of some tools.
2. Some tools are invoked successfully, while others are suspended; the user only provides partial tool results.

Unexpected Result

When resuming, all tools are still executed.
