Fix: missing autoRecallMinRepeated config parsing (follow-up to #40)

[kctony]

問題說明

PR #40 新增了 autoRecall 去重機制，但漏掉了兩個關鍵設定：

1. PluginConfig 介面缺少 autoRecallMinRepeated? 定義
2. parsePluginConfig 函數缺少 autoRecallMinRepeated 解析邏輯

導致 openclaw.json 中的 autoRecallMinRepeated 配置無法正確讀入，功能失效。

修正內容

• 第 42 行：在 PluginConfig 介面新增 autoRecallMinRepeated?: number;
• 第 991 行：在 parsePluginConfig 新增解析邏輯 autoRecallMinRepeated: parsePositiveInt(cfg.autoRecallMinRepeated),

影響範圍

• 不影響現有功能
• 僅補上配置解析邏輯，讓去重機制能正常運作

Hi @kctony, thanks for the follow-up fix for #40!

Just a heads-up — this change (adding autoRecallMinRepeated to PluginConfig + parsePluginConfig) is already included in PR #50 (2nd commit, submitted at nearly the same time).

Merging both PRs as-is will cause a conflict on index.ts. Could you decide which PR should carry this fix?

• If you prefer to keep it in Fix: strip OpenClaw metadata noise in autoCapture and normalizeQuery #50, we can close this one.
• If you prefer this to be standalone, please remove the 2nd commit from Fix: strip OpenClaw metadata noise in autoCapture and normalizeQuery #50.

Let me know which way you'd like to go!

感謝你的修復！這個改動已經包含在 #50 的第二個 commit 中，所以這裡就不重複合併了。再次感謝 🙏
