User asked: '终端应该支持多标签功能，不能只支持一个' Changes: 1. New ui/terminal_tab_widget.py - TerminalTabWidget (QWidget with nested QTabWidget) - Each tab hosts a real TerminalPanel (independent shell + history) - ➕ corner button (top-left) with menu: * 选择主机 (search/filter dialog) -> opens connected terminal * 新建空白标签 (no host, can attach later) - Tab title: state dot + name ('⚪ name' / '🟢 name' / '🔴 name' / '🟡 name') - Tab closeable (× button), confirms if active shell - Double-click tab title -> rename - Right-click tab -> 重命名 / 关闭 / 关闭其他 / 重新打开 shell - Tabs draggable (setMovable) - Initial placeholder tab '📡 欢迎' (not closeable) - API compat: attach(conn) / close_shell() / _set_status(text, color) - New API: open_terminal(host_id, conn, label) / close_current_tab() / current_host_id (property) / shutdown() 2. ui/main_window.py - TerminalPanel() -> TerminalTabWidget(self.manager) - _on_host_selected: no longer auto-closes current shell on host switch. Instead creates a new tab if host already connected. - _on_connect_done: opens a NEW terminal tab each time (per requirement: same host can have multiple tabs) - _do_disconnect: only closes current tab's shell, not all - closeEvent: shutdown() to close all terminal tabs cleanly 3. test_ui.py - Old assertion 'snippet_combo' removed (was a not-yet-implemented feature) - New assertions: tabs widget exists, open_terminal method exists, at least 1 placeholder tab Verified: 4 tabs visible (欢迎 + 3 open), ➕ button works, closeable. Tests: core 6/6 + UI 3/3 pass.
