Code Review

This pull request updates the configuration metadata for Baidu AI search by adding a requirement that the web search toggle must be enabled. It also introduces a unit test to verify this condition. A review comment suggests generalizing this test to iterate through all web search configuration items, ensuring consistent behavior across different providers and better coverage for future additions.

[gemini-code-assist]

目前的回归测试仅针对百度搜索的 Key 进行了校验。为了更好地实现“防止该条件后续再次遗漏”的目标，建议将测试逻辑通用化，遍历 websearch 组下的所有配置项（除开关本身外），确保它们都包含了 provider_settings.web_search: True 的显示条件。这样可以确保所有搜索提供商的配置项在行为上保持一致，并能自动覆盖未来可能新增的配置项。

Suggested change

	def test_baidu_web_search_key_requires_web_search_enabled(self):
	websearch_items = CONFIG_METADATA_3["ai_group"]["metadata"]["websearch"][
	"items"
	]
	condition = websearch_items[
	"provider_settings.websearch_baidu_app_builder_key"
	]["condition"]
	assert condition == {
	"provider_settings.websearch_provider": "baidu_ai_search",
	"provider_settings.web_search": True,
	}
	def test_web_search_items_conditions(self):
	websearch_items = CONFIG_METADATA_3["ai_group"]["metadata"]["websearch"]["items"]
	# 检查所有网页搜索相关的配置项是否都包含了启用网页搜索的条件
	for key, item in websearch_items.items():
	if key == "provider_settings.web_search":
	continue
	condition = item.get("condition", {})
	assert condition.get("provider_settings.web_search") is True, f"{key} 缺少 web_search 启用条件"
	# 验证百度搜索 Key 的特定提供商条件
	baidu_key = "provider_settings.websearch_baidu_app_builder_key"
	assert websearch_items[baidu_key]["condition"]["provider_settings.websearch_provider"] == "baidu_ai_search"
