Fix: 根據最新 PR Review (Qodo, CodeRabbit, Copilot) 進行進一步修正
我針對 PR#863 的最新一輪 review 意見進行了修正，主要包括： 1. **CI Lint `chrome` 未定義問題:** * 我再次確認並標準化 `sidePanel` API 的使用，優先並主要依賴 `Browser.sidePanel`，以解決 CI 環境中的 `chrome is not defined` 問題。 2. **Qodo Merge Pro 高優先級建議:** * **`onBeforeSendHeaders` null 引用:** 我在修改 `headers[i].value` 前，增加了對 `headers[i]` 的存在性檢查。 * **`_proxyOnDisconnect` 競爭條件:** 我改進了監聽器移除邏輯，在移除自身監聽器前，先保存 `port.proxy` 的引用。 * **增強 `SENSITIVE_KEYWORDS`:** 我在敏感詞列表中加入了 `'auth'`, `'key'`, `'credential'`。 * **`redactSensitiveFields` 循環引用:** 我為該函數增加了 `WeakSet` 來檢測和處理循環引用。 * **`manageChatGptTabState` null 檢查:** 我在 `setTimeout` 回調中對 `input.value` 賦值前，增加了對 `input` 的 null 檢查。 * **`prepareForJumpBackNotification` 警告:** 我在 `setInterval` 回調中，如果 `promiseSettled` 已為 true，則添加警告日誌。 3. **`sidePanel` API 跨瀏覽器相容性:** * 我在 `tabs.onUpdated` 監聽器中，實現了更穩健的 `sidePanel.setOptions` 調用邏輯：優先使用 `Browser.sidePanel`，若失敗或不可用，則嘗試 `chrome.sidePanel` (並進行保護性檢查)，均失敗則記錄警告。 所有更改均已通過本地 `npm run lint` 檢查。這些修正旨在進一步提升擴充功能的穩定性、安全性、相容性和程式碼品質。
