feat: collapsible host sidebar (Ctrl+B / view menu / floating restore button)
- ◀ button in sidebar header + '视图→隐藏侧栏 (Ctrl+B)' menu item - collapsed state persisted to ~/.sshclient/settings.json, restored on startup - floating '主机' button (theme-aware dark/light) to re-show sidebar - fix: remove duplicate QShortcut — QShortcut + QAction shortcut on same key both fired, toggling twice per Ctrl+B press (net zero effect) - fix: floating button positioned with parent-local coords instead of mapToGlobal — button no longer drifts off the window edge when the window is not at screen origin; resizeEvent/moveEvent overrides removed - remove dead terminal_input_set_enabled (referenced nonexistent cmd_input) - test_sidebar.py: 7-step coverage incl. single-fire shortcut regression, splitter width restore, cross-restart persistence; settings isolated to tmpdir
