feat(client): B5 install.sh + launchd aider-flush plist

Mac 端安裝腳本：pipx install aider-watch-client → symlink 到 /opt/homebrew/bin →
驗 ~/.aider-watch.env 必要 key → 建 ~/aider-watch 工作目錄 →
載 launchd com.awoooi.aider-flush（每 5min flush buffer）→ 跑 aider-watch doctor。

走 a 路線（LAN direct AIDER_API_URL=http://192.168.0.120:32334/api/v1/aider/events）。
全景檢查：家用場景，B3 buffer + 5min flush 已覆蓋短暫斷網，無需 Tailscale。

+#   2. symlink aiderw 到 /opt/homebrew/bin（讓 PATH 找得到）
+#   3. 檢查 ~/.aider-watch.env（必須有 AIDER_API_URL + AIDER_WEBHOOK_SECRET）
+#   4. 建工作目錄 ~/aider-watch/{buffer,logs}
+#   5. 安裝 launchd flush job（每 5min）
+#   6. 跑 aider-watch doctor 驗證
