feat: add context_window_tokens to model configuration and update related logic

- Introduced context_window_tokens in ModelConfig and LLMProviderConfig structs.
- Updated context window estimation logic in ContextCompressor to use context_window_tokens.
- Modified tests to accommodate new context_window_tokens field.
- Refactored memory maintenance logic into a new memory_maintenance.rs file for better organization.
- Ensured backward compatibility by providing default values where necessary.

 1. 系统先对当前活动历史做一个近似 token 估算。
 	估算规则不是调用 tokenizer，而是按“约每 4 个字符约等于 1 token，并再乘以 1.2 安全系数”计算。
 2. 当估算结果超过模型上下文窗口的 50% 时，压缩器才认为“需要压缩”。
-	这里的上下文窗口来自 agent 对应模型配置里的 token_limit。
+	这里的上下文窗口来自 agent 对应模型配置里的 context_window_tokens；未配置时按 128000 估算。
 3. 即使超过阈值，如果当前历史里的 user turn 数量不超过保留阈值，也不会压缩。
 	当前默认会完整保留最近 3 个 user turn。
 4. 一旦满足条件，压缩器会先按 user 消息切分 turn，再确定“旧历史”和“最近保留段”的分界点。
