Greptile Summary

The changes in cocos/game/splash-screen.ts add checks for the WECHAT constant to disable the splash screen for the WeChat mini game platform.

• Added if (WECHAT) { return; } checks in init(), preInit(), initLayout(), initScale(), update(), initBG(), initLogo(), initWaterMark(), frame(), and destroy() methods.
• Ensures splash screen is bypassed entirely on WeChat platform.
• No impact on other platforms; functionality remains unchanged.
• No security issues or logical errors detected.
• Verify no dependencies on splash screen functionality elsewhere in the codebase.
