refactor: 移除未使用的 IsChannelObjectPublic 方法
优化历程： 1. 最初添加 IsChannelObjectPublic() 用于空间索引中逐个检查对象 2. 后续优化为 GetNonChannelGeometryItemsCache() 在缓存层预过滤通道 3. IsChannelObjectPublic() 方法已不再被使用，删除以保持代码整洁 私有方法 IsChannelObject() 保留，仍在缓存构建时使用 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
