Fix nil pointer panic in TYC searchBaseInfo when HTML element missing

[Copilot]

Tianyancha API queries panic with "invalid memory address or nil pointer dereference" when cookie authentication fails or page structure changes.

Changes

• Added nil check in searchBaseInfo: Guard against missing __NEXT_DATA__ HTML element before calling htmlquery.InnerText()
• Added empty array validation: Check enInfoD length to prevent index out of bounds access
• Improved error messages: Return descriptive errors directing users to verify cookie configuration

Technical Details

When htmlquery.FindOne() fails to locate the __NEXT_DATA__ script tag (typically due to invalid/expired cookies), it returns nil. The previous code immediately dereferenced this nil pointer:

htmlInfos := htmlquery.FindOne(body, "//*[@id=\"__NEXT_DATA__\"]")
enInfo := gjson.Parse(htmlquery.InnerText(htmlInfos))  // panic if htmlInfos is nil

Now validates before dereferencing:

htmlInfos := htmlquery.FindOne(body, "//*[@id=\"__NEXT_DATA__\"]")
if htmlInfos == nil {
    gologger.Error().Msgf("【TYC】COOKIE检查失效，请检查COOKIE是否正确！\n")
    return gjson.Result{}, gjson.Result{}
}
