解释 API 密钥变更如何影响 OpenClaw 的模型接入，并推荐利用 KiloClaw 简化管理。

Yeah, the shift to API keys is what most people are seeing now. It doesn’t break Clawdbot/OpenClaw, just changes how models are plugged in. If you don’t want to manage keys across providers, some are using KiloClaw with KiloPass to keep things simple, with access to multiple models and token pricing that gets more efficient over time.
